Available in PDF, EPUB and Kindle. Book excerpt: This paper is concerned with describing a damage mechanics formulation which provides for non-isotropic effects using a scalar damage variable. An investigation has been in progress for establishing the constitutive behavior of rock salt at long times and low to moderate confining pressures in relation to the possible use of excavated rooms in rock salt formations as repositories for nuclear waste. An important consideration is the effect of damage manifested principally by the formation of shear induced wing cracks which have a stress dependent orientation. The analytical formulation utilizes a scalar damage parameter, but is capable of indicating the non- isotropic dependence of inelastic straining on the stress state and the confining pressure. Also, the equations indicate the possibility of volumetric expansions leading to the onset of tertiary creep and eventually rupture if the damage variable reaches a critical value.

Download or read book Continuum Damage Mechanics and Numerical Applications written by Wohua Zhang and published by Springer Science & Business Media. This book was released on 2010-11-19 with total page 937 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Continuum Damage Mechanics and Numerical Applications" presents a systematic development of the theory of Continuum Damage Mechanics and its numerical engineering applications using a unified form of the mathematical formulations in anisotropic and isotropic damage models. The theoretical framework is based on the thermodynamic theory of energy and material dissipation and is described by a set of fundamental formulations of constitutive equations of damaged materials, development equations of the damaged state, and evolution equations of micro-structures. According to concepts of damage-dissipation of the material state and effective evolution of material properties, all these advanced equations, which take nonsymmetrized effects of damage aspects into account, are developed and modified from the traditional general failure models so they are more easily applied and verified in a wide range of engineering practices by experimental testing.

Available in PDF, EPUB and Kindle. Book excerpt: The formulation of a rectangular plate vibration with anisotropic damage is presented in this report. The governing equations are derived by manipulating the general displacement theory, and the anisotropic damage model developed by Valliappan, Zhang and Murti. The equations are then solved using the finite element (FE) method. Using a particular quantitative example, it can be shown that an anisotropic damage will down-shift the frequency spectrum of the plate significantly. (author abstract)

This book was released on 2012-11-27 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scope of this book is based on the keynote lectures delivered during the Inter national Symposium on Anisotropic Behaviour of Damaged Materials ABDM, held in Krakow-Przegorzaiy, Poland, September 9-11, 2002. The Symposium was organized by the Solid Mechanics Division of the Institute of Mechanics and Machine Design - Cracow University of Technology, under aus pices of the Dean of the Faculty of Mechanical Engineering, Cracow University of Technology, Prof. S. Michalowski. The Co-organizers of the ABDM Symposium were: • Martin-Luther-Universitat Halle-Wittenberg, • Centre of Excellence for Advanced Materials and Structures AMAS at the In stitute of Fundamental Technological Research of the Polish Academy of Sci ences, Warsaw, • Committee of Mechanics of the Polish Academy of Sciences, Warsaw. Ten chapters of this book in their present form essentially exceed lectures de livered at the Symposium. They should rather be read as not only author's recent achievements in the field, but also the state of art and synthesis done by the lead ers in the mechanics community. The mixed formula of the Symposium, namely: the invited lectures and presentations of the original papers by the participants was used. 23 original papers, published in the Symposium Proceedings on CD, exhaust the full scope of the ABDM Symposium. The present book provides a survey of various damage models focusing on the damage response in anisotropic materials as well as damage-induced anisotropy.

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.

Download or read book Dynamic Rate Dependent Elastoplastic Damage Modeling of Concrete Subject to Blast Loading Formulation and Computational Aspects written by and published by . This book was released on 1990 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced elastic-damage and elastoplastic-damage models are presented within the frameworks of both continuum damage mechanics and micromechanical damage mechanics. Novel energy-based coupled elastoplastic continuum damage theories and computational algorithms are proposed, including rate-dependent isotropic and anisotropic damage models. Efficient constitutive algorithms and extensive experimental validations are also performed. In addition, novel finite deformation elastoplastic continuum damage models are developed to account for large strains and high rates. On the other hand, advanced and state-of-the-art two- and three-dimensional micromechanical anisotropic damage models are proposed to physically simulate micromechanical microcracking kinetics (cleavage 1 and cleavage 2 processes) and damaged overall compliances for concrete materials under tensile and compressive loadings. These results are innovative, fundamental, and very useful in advanced damaged modeling.
