Book Finite Inelastic Deformations     Theory and Applications

Download or read book Finite Inelastic Deformations Theory and Applications written by Dieter Besdo and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IUTAM-Symposium on "Finite Inelastic Deformations - Theory and Applications" took place from August 19 to 23, 1991, at the University of Hannover, Germany, with 75 participants from 14 countries. Scope of the symposium was a fundamental treatment of new developments in plasticity and visco-plasticity at finite strains. This covered the phenomenological material theory based on continuum mechanics as well as the treatment of microstructural phenomena detected by precise experimental datas. In a restricted number, lectures on new experi mental facilities for measuring finite strains were also implemented into the symposium. Another important topic of the symposium was the treatment of reliable and effective computational methods for solving engineering problems with finite inelastic strains. Wi thin this context it was an essential feature that theory, numerical and computational analysis were be seen in an integrated way. In total 9 sessions with 37 lectures, many of them given by well known keynote-lecturers, and a poster session with 10 contributions met fully our expectations of a high ranking up-to-date forum for the interaction of four topics, namely the physical and mathematical modelling of finite strain inelastic deformations including localizations and damage as well as the achievements in the numerical analysis and implementation and the solution of complicated engineering systems. Special and important features were reliable material datas from macroscopic and microscopic tests as well as test results of complex engineering problems, like deep drawing and extrusion.

Book Constitutive Equations for Engineering Materials

Download or read book Constitutive Equations for Engineering Materials written by Wai-Fah Chen and published by Elsevier. This book was released on 2013-10-22 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: Constitutive Equations for Engineering Materials, Volume 1: Elasticity and Modeling, Revised Edition focuses on theories on elasticity and plasticity of engineering materials. The book first discusses vectors and tensors. Coordinate systems, vector algebra, scalar products, vector products, transformation of coordinates, indicial notation and summation convention, and triple products are then discussed. The text also ponders on analysis of stress and strain and presents numerical analysis. The book then discusses elastic stress-strain relations. Basic assumptions; need for elastic models; isotropic linear stress-strain relations; principle of virtual work; strain energy and complementary energy density in elastic solids; and incremental relations grounded on secant moduli are described. The text also explains linear elasticity and failure criteria for concrete and non-linear elasticity and hypoelastic models for concrete. The selection further tackles soil elasticity and failure criteria. Mechanical behavior of soils; failure criteria of soils; and incremental stress-strain models based on modification of the isotropic linear elastic formulation are considered. The text is a good source of data for readers interested in studying the elasticity and plasticity of engineering materials.

Book excerpt: Inelastic Analysis of Solids and Structures presents in a unified manner the physical and theoretical background of inelastic material models and computational methods, and illustrates the behavior of the models in typical engineering conditions. The book describes experimental observations and principles of mechanics, and efficient computational algorithms for stress calculations as typically performed in finite element analysis.

Book Constitutive Modeling and Numerical Implementation of Brittle and Ductile Material Behavior with the Aid of Inelastic XFEM and Damage plasticity Models

Download or read book Constitutive Modeling and Numerical Implementation of Brittle and Ductile Material Behavior with the Aid of Inelastic XFEM and Damage plasticity Models written by Shahriyar Beizaee and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Constitutive equations establish the relationship between kinetic with kinematic quantities to characterize the specific properties of the material. Mechanical constitutive relations are formulated to describe nonlinear and inelastic response behavior as well as brittle or ductile failure of metallic and cementitious materials in form of plastic and damage material formulations. This dissertation addresses three topics: The first topic is focused on the peak response behavior of brittle and ductile materials by coupling plasticity with extended finite element method in order to model and follow discrete crack initiation and fracture propagation. This is accomplished by exploiting appropriate crack initiation criteria and performing analytical and numerical localization analysis to determine the critical orientation of the emerging failure surface. A series of experiments are performed on perforated metallic flat bars and the observations are used to validate the computational failure predictions. The second topic is the finite element approximation of the field data obtained by photogrammetric non-contact digital image correlation analysis. This study includes experimental observations on various perforated metallic flat bars to evaluate displacements and strains by using digital image correlation analysis. The displacement images are used in order to determine the best approximation of finite element nodal displacement values based on least square approximation of the optical measurement data. Moreover, infinitesimal and finite strains are calculated and contrasted with the results processed by the commercial Aramis imaging software. The last topic is focused on the localization of triaxial concrete behavior by a damage-plasticity model. In this constitutive formulation a three-invariant yield function is introduced to model plastic deformations and a damage function is used to determine the nonlinear and inelastic behavior of concrete. Coupling of the inelastic damage and plasticity processes is introduced by a damage variable that enters the plastic yield function in terms of the effective stress. Localization properties of the combined damage-plasticity model are studied and the differences of the damage vs. plasticity constituents are explored and compared. A series of experimental tests are performed on concrete cylinders in cyclic compression and digital images are recorded to provide complementary field data of surface deformations and cracks.

Book Constitutive Models for Rubber IV

Download or read book Constitutive Models for Rubber IV written by Per-Erik Austrell and published by Routledge. This book was released on 2017-12-04 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unique properties of elastomeric materials offer numerous advantages in many engineering applications. Elastomeric units are used as couplings or mountings between rigid components, for example in shock absorbers, vibration insulators, flexible joints, seals and suspensions, etc. However, the complicated nature of the behaviour of such material makes it difficult to accurately predict the performance of these units using finite element modelling, for example. It is imperative that constitutive models accurately capture relevant aspects of mechanical behaviour. The latest developments concerning constitutive modelling of rubber is collected in these Proceedings. Topics included in this volume are, Hyperelastic models, Strength, fracture & fatigue, Dynamic properties & the Fletcher-Gent effect, Micro-mechanical & statistical approaches, Stress softening, iscoelasticity, Filler reinforcement, and Tyres, fibre & cord reinforced rubber.

They progress to explain a finite elastoplastic constitutive model, discuss numerical issues on stress computation, implement the numerical algorithms for stress computation into large-deformation finite element analysis and illustrate several numerical examples of boundary-value problems. Programs for the stress computation of finite elastoplastic models explained in this book are included in an appendix, and the code can be downloaded from an accompanying website.
