We present a novel numerical method to simulate crack growth in 3D, directly from the Computer-Aided Design (CAD) geometry of the component, without any mesh generation. The method is an isogeometric boundary element ...

This paper addresses the numerical solution of random crack propagation problems using the coupling boundary element method (BEM) and reliability algorithms. Crack propagation phenomenon is efficiently modelled using BEM, ...

In this work, we study the emergence of different crack modes in linearly elastic thin films by means of a Gamma-convergence analysis as the thickness tends to zero. We first consider a purely elastic body made of a film ...

The present investigation is concerned with evaluation of the impact fracture toughness of novel blends based on commercial polypropylene homopolymer (PPH) and elastomeric polyolefin (POEs). At room temperature and high ...

The study of fracture mechanics is directed to the analysis of the capability of the material to resist mechanical stress without the occurrence of failure. The presence of small cracks can reduce the structural strength ...

The linear elastic fracture mechanics (LEFM) allows quantification of the relationship between the material properties, the stress level, the presence of crack-generating defects and crack propagation mechanisms. There ...

This paper proposes a boundary element method (BEM) model that is used for the analysis of multiple random crack growth by considering linear elastic fracture mechanics problems and structures subjected to fatigue. The ...

The formulation of a phase-field continuum theory for brittle fracture in elastic–plastic solids and its computational implementation are presented in this contribution. The theory is based on a virtual-power formulation ...
