Peridynamic Modeling of Thermo-Oxidative Damage Evolution in a Composite Lamina

Abstract

Surface oxidation degrades the durability of polymer marix composites operating at high temperatures due to the presence of strong coupling between the thermal oxidation and structural damage evolution. The mechanism of oxidation in polymer matrix composites leads to shrinkage and damage growth. The thermo-oxidative behavior of composites introduces changes in diffusion behavior and mechanical response of the material. This study presents the derivation of peridynamic formulation for the thermo-oxidative behavior of the polymer matrix composites. As a demonstration purposes, isothermal aging of a unidirectional composite lamina is presented by using peridynamics. Oxidation contributed to the damage growth and its propagation.

Peridynamics for geometrically nonlinear analysis of three-dimensional beam structures

“…To date, PD theory has been implemented in many fields such as nonlinear elastic or inelastic material responses [21][22][23][24][25][26], multiphysics [27][28][29][30][31][32][33][34][35][36][37][38], multiscale modelling [39,40], orthotropic material responses [41][42][43][44], and fatigue cracking [45][46][47]. Moreover, it can also be either combined with finite element analysis (FEA) [41,[48][49][50] or implemented in the FEA framework [31,[51][52][53][54].…”

Fluid-elastic structure interaction simulation by using ordinary state-based peridynamics and peridynamic differential operator

“…Consequently, non-ordinary state-based [17] and ordinary state based [16] peridynamic formulations are developed to overcome the Poisson's ratio limitations. The PD theory has been mainly applied for predicting damages in structures due to various loading conditions [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. In fluid structure interaction problems, capability of numerical models is required for predicting damages.…”

Coupled thermo-fluid-mechanical peridynamic model for analysing composite under fire scenarios

“…Then, the formulation is extended for modelling damage in composite materials [36][37][38][39][40][41][42][43][44][45][46][47][48][49]. The original form of PD is also extended for predicting thermal damages for both isotropic [50][51][52][53] and composite materials [54][55][56][57][58]. Moreover, PD is also used for predicting corrosion and oxidation damage for both isotropic and composite materials [50,56,[59][60][61][62].…”

“…The original form of PD is also extended for predicting thermal damages for both isotropic [50][51][52][53] and composite materials [54][55][56][57][58]. Moreover, PD is also used for predicting corrosion and oxidation damage for both isotropic and composite materials [50,56,[59][60][61][62]. Therefore, due to the prediction capability of PD in many different applications, in this study PD is used to predict the composite damage under fire scenarios.…”
