Available in PDF, EPUB and Kindle. Book excerpt: A numerical investigation has been conducted on the strain rate dependent compression mechanical behavior of a SiC-particulate reinforced Al (2024-O) metal matrix composite. The effect of particle volume fraction on the strain rate sensitivity of the composite was determined using axisymmetric Finite Element unit cell models, where the particles are treated as elastic spheres embedded within a visco-plastic matrix, implemented in LUSAS Finite Element Analysis program. Particles are taken to be elastic, equal-sized, spherical and uniformly distributed in the matrix. The strain rate dependent constitutive behavior of the matrix material uses a linear relation between stress and strain rate formulation and is obtained from independent experimental results on the matrix. The flow stress of the composites is predicted over a range of strain rates for different particle volume fractions. Numerical results of the flow stress and strain rate sensitivity of the composite were also compared with those of experimental results, for 15% SiC particle reinforced 2024-O Al metal matrix composite. Influence of particle shape on the behavior of the MMC at high strain rates is also investigated. A unit cell, which is an elastic cylinder embedded within a visco-plastic matrix, is used. It is also shown that the rate dependent flow stress and local stress in the microstructure are influenced by particle shape. If reinforcement edge sharpness increases, local stress increases at that area. The results show that both the flow stress and the strain rate sensitivity increase with increasing volume fraction of the reinforcement due to the constraining effect of the reinforcement. Numerical calculations have shown an increased strain rate sensitivity of the composite over the matrix alloy. The discrepancy found between numerical and experimental results was finally discussed based on geometrical and microstructural parameters that might affect the composite flow stress and strain rate sensitivity.

This book was released on 2022-10-31 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the results of experimental and theoretical studies of the destruction of solids under impact, explosion, high pressures, and strain rates. The content identifies the basic laws of the destruction of bodies under dynamic loads. The results of numerical studies were obtained using numerical methods on the Lagrangian, Euler, and ALE approaches to the description of the motion of continuous media. Numerical methods and mathematical models have been tested by comparison with experimental data and well-known analytical solutions (for instance, Rankin–Hugoniot laws). Experimental studies were performed on unique ballistic installations with the registration of fast processes (high-speed shooting). The results are used as new tests to verify the developing modeling methods. The research objects were metal multilayer plates, functionally graded materials, advanced, smart, and natural materials, etc. The book is interesting to specialists in the field of mathematical modeling and experimental methods for studying fast processes under dynamic loading.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Cold spray has demonstrated great promise in developing particle-reinforced metal matrix composites, which combine the high strength and toughness of metals with those of excellent wear resistance, corrosion resistance and chemical stability of ceramics. However, the understanding of mechanisms underlying the retention of ceramics in the coatings remains inadequate, making it difficult to develop optimizing strategies to manufacture composite coatings with better properties. Therefore, aiming to gain a deeper understanding of the ceramic retention behavior, the present thesis systematically investigated various key aspects through computational modeling, including the effect of varying the spraying parameters, the influence of substrate roughness and ceramic fracture/fragmentation on its retention behavior. The first part of the investigations focused on the effect of impact angles on the retention and embedding behavior of the ceramic particles. It was concluded that off-normal impact angle promoted the retention possibility of ceramics in the substrate by enhancing the contact strength, increasing the contact time and reducing the rebounding velocity. Moreover, it was also demonstrated that substrate material erosion increased as the impact angles decreased from normal.The second part involved simulations of the first-layer ceramic deposition involving ceramic particle and metal substrates. For soft substrates, crater depth was found to be the key factor in determining ceramic retention. While the ceramic retention was also greatly affected by the occurrence of jetting at the crater edges. Furthermore, it was demonstrated that substrate roughness could promote ceramic retention by mitigating jetting and increasing the crater depth.To account for the increase in flow stress at high strain-rates experienced during cold spray, a power law-based modification of Johnson-Cook model was proposed for the third investigation. Additionally, a strain gradient plasticity-based model was also proposed to accurately predict the cold sprayed particle’s shape consistent with the experimental observations in the literature.The final part of the investigation focussed on the dynamic behavior of micron-sized ceramic particles. Through a polycrystalline model, the fragmentation and retention of ceramic particles were studied concerning to grain size, impact velocity and grain boundary properties. It was demonstrated that grain size has an important role in determining the retention in the coating. Moreover, lower fragmentation and higher retention of ceramic particles were predicted during spraying a mixture of metal and ceramic particles onto a metal substrate. These studies offer new mechanistic insights into ceramic-metal interactions, and more generally, new knowledge and modeling tools to guide the design of better composite coatings through cold spray"--

Book excerpt: Metal Matrix Composites: Thermomechanical Behavior discusses metal matrix composites, elaborating on that consists of two phases—fiber as reinforcement and metal as matrix. This book focuses on polymer matrix composites, including topics in metal matrix composites ranging from processing to fracture mechanics. The three basic types of composite materials—dispersion-strengthened, particle-reinforced, and fiber (whisker)-reinforced, are also described in detail. Dispersion-strengthened is characterized by a microstructure consisting of an elemental matrix within which fine particles are uniformly dispersed, while particle-reinforced is indicated by dispersed particles of greater than 1.0 μm diameter with a volume fraction of 5 to 40%. Fiber (whisker)-reinforced provides a distinguishing microstructural feature of fiber-reinforced materials, such as that the reinforcing fiber has one long dimension, while the reinforcing particles of the other two types do not. This publication serves as a reference data book to students and researchers aiming to acquire knowledge of the thermomechanical behavior of metal matrix composites.

Available in PDF, EPUB and Kindle. Book excerpt: The dynamic behavior of metal matrix composite (MMC) plates is considered. In particular, the influence of inelastic deformations and delamination at the interfaces of the lamina on the macroscopic and local response of Al2O3/Al plates are studied. The work is carried out using a recently developed plate theory which models both delamination and localized history-dependent effects such, as inelasticity. A linear debonding model for the interface is employed for the current work. The theory models both the initiation and growth of delaminations without imposing any restrictions on the location, size, or direction of growth of the delamination. In the current work the response of the individual lamina in the plate are modeled using the Method of Cells (MOC) micromechanical model. The inelastic behavior in the matrix is modeled using the unified viscoplastic theory of Bodner and Partom. The behavior of a Al2O3/Al plate under dynamic cylindrical bending subjected to a ramp and hold type of loading is examined. For simplicity, the plate is assumed to be composed of a cross-ply layup. It is shown that both inelastic deformations and delamination have a strong influence on dynamic plate behavior. The inelastic deformations have strong effect on the axial displacement while delamination has greater influence on the deflection.

Download or read book Advances in Damage Mechanics Metals and Metal Matrix Composites written by George Voyiadjis and published by Elsevier. This book was released on 2012-12-02 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides in a single and unified volume a clear and thorough presentation of the recent advances in continuum damage mechanics for metals and metal matrix composites. Emphasis is placed on the theoretical formulation of the different constitutive models in this area, but sections are added to demonstrate the applications of the theory. In addition, some sections contain new material that has not appeared before in the literature. The book is divided into three major parts: Part I deals with the scalar formulation and is limited to the analysis of isotropic damage in materials; Parts II and III deal with the tensor formulation and is applied to general states of deformation and damage. The material appearing in this text is limited to plastic deformation and damage in ductile materials (e.g. metals and metal matrix composites) but excludes many of the recent advances made in creep, brittle fracture, and temperature effects since the authors feel that these topics require a separate volume for this presentation. Furthermore, the applications presented in this book are the simplest possible ones and are mainly based on the uniaxial tension test.
