Download or read book Finite Element Approach for Calculating the Stress Wave Attenuation Through a Polymer Matrix Composite written by Shrikant Shyam Nargund and published by . This book was released on 2014 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dynamic behavior of polymer composites is significantly affected by the properties of their micro constituents including shape and size of inclusions and inclusions/matrix adhesion properties. Finite element modeling provides a viable approach for investigating the effects of micro constituent structure on the dynamic behavior of polymer composites. In this thesis, finite element (FE) modeling is used to investigate wave propagation through polymer matrix particulate composite. This finite element models consists of three phases; polymer matrix, particle reinforcements and interphase zones between inclusions and matrix. The interphase zones are modeled explicitly to study how the properties of interphase can affect the dynamic behavior of the polymer. Interphase region physically indicates a coupling agent added in between the two materials which improve bonding as well as reduce stress concentration at the interface. By performing analysis on three dimensional finite element models, the attenuation characteristic of ultrasonic longitudinal waves in the composite are evaluated. An interface between polymer and inclusions is modeled by Cohesive Zone Modeling (CZM) implementing bilinear traction separation law. We specifically investigate how to maximize the wave attenuation in composite by changing the size, volume fraction of inclusions and interphase material properties. The effect of frequency of wave on wave attenuation is also studied by varying the frequency in between 1MHz and 4MHz. The analysis is performed using the finite element software LS-Dyna and models are prepared using pre-processing software Hypermesh. Results of the tests revealed that higher volume fraction of inclusions give a greater attenuation compared to lower volume fraction model. Also small size of inclusions is preferred over lager size as they give higher wave attenuation. Results are also affected by the arrangement/ distribution of the inclusions. Softer interphase zone (low stiffness) performs better in absorbing the incident wave energy, hence giving higher wave attenuation than harder (high stiffness) interphase.

Available in PDF, EPUB and Kindle. Book excerpt: Mechanical properties of composite materials can be improved by tailoring their microstructures. Optimal microstructures of composites, which ensure desired properties of composite materials, can be determined in computational experiments. The subject of this book is the computational analysis of interrelations between mechanical properties (e.g., strength, damage resistance stiffness) and microstructures of composites. The methods of mesomechanics of composites are reviewed, and applied to the modelling of the mechanical behaviour of different groups of composites. Individual chapters are devoted to the computational analysis of the microstructure- mechanical properties relationships of particle reinforced composites, functionally graded and particle clusters reinforced composites, interpenetrating phase and unidirectional fiber reinforced composites, and machining tools materials.

Download or read book Residual Stresses in Composite Materials written by Mahmood M. Shokrieh and published by Woodhead Publishing. This book was released on 2014-02-14 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residual stresses are a common phenomenon in composite materials. They can either add to or significantly reduce material strength. Because of the increasing demand for high-strength, light-weight materials such as composites and their wide range of applications in the aerospace and automotive industries, in civil infrastructure and in sporting applications, it is critical that the residual stresses of composite materials are understood and measured correctly.The first part of this important book reviews destructive and non-destructive testing (NDT) techniques for measuring residual stresses. Various mathematical (analytical and numerical) methods for calculation of residual stresses in composite materials are also presented. Chapters in the first section of the book discuss the simulated hole drilling method, the slitting/crack compliance method, measuring residual stresses in homogeneous and composite glass materials using photoelastic techniques, and modeling residual stresses in composite materials. The second part of the book discusses residual stresses in polymer matrix, metal-matrix and a range of other types of composites. Moreover, the addition of nanoparticles to the matrix of polymeric composites as a new technique for reduction of residual stresses is discussed.Residual stresses in composite materials provides a comprehensive overview of this important topic, and is an invaluable reference text for both academics and professionals working in the mechanical engineering, civil engineering, aerospace, automotive, marine and sporting industries. - Reviews destructive and non-destructive testing (NDT) techniques for measuring residual stresses - Discusses residual stresses in polymer matrix, metal-matrix and other types of composite - Considers the addition of nanoparticles to the matrix of polymeric composites as a new technique for reduction of residual stresses

Download or read book Numerical Simulation of Mechanical Behavior of Composite Materials written by Sergio Oller and published by Springer. This book was released on 2014-09-04 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: An original mechanical formulation to treat nonlinear orthotropic behavior of composite materials is presented in this book. It also examines different formulations that allow us to evaluate the behavior of composite materials through the composition of its components, obtaining a new composite material. Also two multiple scale homogenization methods are given, one based on the analytical study of the cells (Ad-hoc homogenization) and other one, more general based on the finite element procedure applied on the macro scale (upper-scale) and in the micro scale (sub-scale). A very general formulation to simulate the mechanical behavior for traditional composite structures (plywood, reinforced concrete, masonry, etc.), as well as the new composite materials reinforced with long and short fibers, nanotubes, etc., are also shown in this work. Typical phenomena occurring in composite materials are also described in this work, including fiber-matrix debonding, local buckling of fibers and its coupling with the overall buckling of the structure. Finally, several numerical examples that evaluates the qualities and capabilities of the general model formulated are offered in this book. This book is intended for graduate engineering students who want to expand their knowledge of composite structures behavior.
