XFEM Fracture Analysis of Composites

Angebote / Angebote:

The extended finite element method (XFEM) is an extension to the classical finite element method (FEM), using the concepts of partition of unity and meshless approaches. It is specifically designed to improve the performance of the conventional finite element method, while keeping the computational costs at an acceptable level, and avoiding the ambiguities and implications of FEM in mesh propagation problems. XFEM has now been widely adopted by civil, mechanical, material and aerospace engineering disciplines all over the world and is used to accurately determine the level of performance and safety of cracked structures. XFEM Fracture Analysis of Composites presents the new developments in the XFEM for fracture analysis of composites, including static and dynamic fracture analysis, layer cracking and multilayer delamination, and cracking of inhomogeneous functionally graded materials (FGMs). This book also introduces new computational frontiers of fracture analysis of orthotropic materials, including the recently developed extended isogeometric analysis (XIGA), XFEM anisotropic dislocation dynamics, biomechanical applications, and piezoelectric materials. Key features include: * Comprehensive description of the extended finite element method * Complete theoretical bases, before exploration of numerical issues * Coverage of static and dynamic crack propagation of composites and functionally graded materials, and delamination in bimaterial composites * Introduction of the extended isogeometric analysis for orthotropic materials * Accompanied by a website (www.wiley.com/go/mohammadi) hosting sample MATLAB(r) files XFEM Fracture Analysis of Composites is a comprehensive text ideal for graduate and postgraduate students and is a useful reference for researchers and practising engineers involved in cracking and fracture mechanics.
