The book aims to discuss the latest developments in computational theories on multiple-crack analysis and mixed-mode fracture in structural concrete and the application of these theories to solve important engineering problems.

Numerical Modelling of Failure in Advanced Composite Materials comprehensively examines the most recent analysis techniques for advanced composite materials. Advanced composite materials are becoming increasingly important for lightweight design in aerospace, wind energy, and mechanical and civil engineering.

Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture.

In modern materials science, fracture mechanics is an important tool used to improve the. • Analysis techniques for delamination/crack modelling: – J-Integral – Virtual Crack Closure Technique (VCCT) – Cohesive Zone Modelling (CZM) – Refined mesh around crack tip – Problems in 3D and unloading (non-linear elastic material assumption) mechanics) and direction for crack propagation • Numerical integration and.

This book introduces the development of the extended finite element method for fracture mechanics and crack analysis.

Hi Muhammad, I just get back from Abaqus workshop for modeling Fracture and Failure with Abaqus. For the background you need the following: 1-Fracture mechanics book for Anderson. It has lots of examples. 2-If you can by the handout for the workshop you will have a complete examples on how to do crack analysis and crack probagation.

it available on of you want to buy it. The fictitious crack is represented by interface elements with linearly varying displacements; however, the traction distribution is arbitrary. As example problems demonstrate, these assumptions allow the fictitious crack to be modeled using few degrees of freedom without compromising accuracy.

Modeling of the size effect is presented. The relevant concepts, theory and modelling issues of the scaled boundary finite element method are discussed and the unique features of the method are highlighted.

The applications in computational fracture mechanics are detailed with numerical examples. A unified mesh generation procedure based on quadtree/octree algorithm is described.

Boundary element formulations in fracture mechanics: a review M.H Aliabadi, C.A. Brebbia of modelling crack problems in BEM. General mixed-mode crack problems can be solved [28]. Other special crack tip elements for modelling the near crack tip behaviour are reported by Aliabadi[31], Jia, Shippy and Rizzo[32] for two.The crack propagation direction is assumed to be perpendicular to the direction of the maximum tensile principal stress at the cohesive crack tip.

A generalized virtual crack-extension technique including the cohesive crack model is used to efficiently evaluate the crack propagation condition.
