This paper presents a simple and computationally efficient multi-scale procedure to predict the macroscopic temperature dependent coefficient of thermal expansion (CTE) of any linearly thermoelastic material from isothermal mechanical simulations onl

This paper presents the development of a Cellular Automaton (CA) capable of describing polycrystalline structures heterogeneous behavior in the elastic domain. Based on Eshelby’s inclusion problem, this model is the first step to a better considera

Polycrystals are full of all kinds of heterogeneities which introduce stress concentrations. The local stress field in a grain does not depend solely on its crystallographic orientation. In fact, its neighborhood has also been shown to play a signifi

This work aims at modeling the homogenized behavior of a polymer matrix composite reinforced with three dimensional (3D) woven fabric. The effective warp and weft tows’ properties were determined by numerical homogenization with Abaqus considering

This paper presents an inverse methodology relying on finite element simulation based optimization to extract material constitutive parameters from a single spherical indentation, which are used to estimate its bulk true stress-true strain curve. Met

Linearly viscoelastic constitutive theories are usually expressed as a Prony series involving fourth order tensors and retardation times. Obtaining the numerical values of the terms involved in such constitutive models from experiments is an ill-pose

The temperature effect on the tensile behavior of a triaxially braided composite was investigated in two different loading directions. The damage evolution was monitored and the results were explained with the help of experimental, analytical and num

This paper validates the performance of analytical homogenization models at predicting the local field statistics in randomly distributed and oriented ellipsoidal particles reinforced composites. The numerical validation was based on a newly introduc

This paper presents an identification procedure based on the Virtual Fields Method (VFM) for identifying in situ mechanical properties of composite materials constitutive phases from 3D full-field measurements. The new procedure, called the Regulariz

Accurate numerical homogenization necessitates the thorough determination of the Representative Volume Element (RVE). There exists several seminal works on the notion of the RVE in homogenization, its definitions and methods of determination for effi
