Damage mechanics offers the possibility of representing the failure of components directly, without the use of characterising parameters such as the K or J of fracture mechanics. It does so by allowing the material to develop damage and fail at the level of the continuum mechanics description. Within the regime of ductile fracture, the method tries to encapsulate the loss of strength associated...

The aim of this research is to assess the effects of interphase property and matrix property on the tensile elastic modulus (TEM) of the carbon nanotube (CNT) using a 3-D nanoscale representative volume element (RVE) based on continuum mechanics and using the finite element method (FEM). Formulas to extract the effective material constants from solutions for the RVE is derived based on the elas...

The present paper presents a three-dimensional composite damage model for predicting the crush response of thin-walled structures, i.e., cylindrical tubes, manufactured employing fibre-reinforced polymer–matrix composites. This computational is based upon Continuum Damage Mechanics (CDM) approach and accounts both intralaminar interlaminar as well nonlinear behaviour that occur in materials. Ex...

In sheet metal forming processes with complex strain paths, a part is subjected to large plastic deformation. This severe plastic deformation leads to high plastic strain localization zones and subsequent accumulation of those strains. Then internal and superficial micro-defects and in other words ductile damage is created. This damage causes quality problems such as fracture. Therefore, design...
