Stochastic analysis of the fracture toughness of polymeric nanoparticle composites using polynomial chaos expansions
Khader M. Hamdia,Khader M. Hamdia,Mohammad Silani,Xiaoying Zhuang,Pengfei He,Timon Rabczuk,Timon Rabczuk +6 more
TL;DR: In this article, the authors presented a methodology for stochastic modeling of the fracture in polymer/particle nanocomposites, which is based on six uncertain parameters: the volume fraction and the diameter of the nanoparticles, Young's modulus and the maximum allowable principal stress of the epoxy matrix, the interphase zone thickness and its Youngs modulus.
Journal ArticleDOI

Mohammed A. Msekh,Mohammed A. Msekh,Mohammad Silani,Mohammad Silani,M. Jamshidian,Pedro M. A. Areias,Xiaoying Zhuang,Goangseup Zi,Pengfei He,Timon Rabczuk +9 more
TL;DR: In this paper, a phase field approach is used to predict macroscopic fracture related material parameters of fully exfoliated clay/epoxy nanocomposites based on their fine scale features.
Journal ArticleDOI
Fracture toughness of polymeric particle nanocomposites: Evaluation of models performance using Bayesian method
TL;DR: In this article, the performance of different models used in predicting the fracture toughness of polymeric particles nanocomposites is evaluated with respect to the experimental data, using the Bayesian method.
Journal ArticleDOI
A dynamic XFEM formulation for crack identification
TL;DR: In this article, the effects of various dynamical test loads on the crack identification were investigated for a time- harmonic excitation with a single frequency and a short-duration signal measured along part of the external boundary.
Journal ArticleDOI
