Abstract: Present work describes the crack growth characteristics in orthotropic composite materials by utilizing extended finite element analysis under combined thermal-mechanical loading conditions. In combined system, temperature and displacement approximations are extrinsically governed by additional functions to define discontinuity profile across crack surface. In present work, two step simulation methodologies are adopted where thermal discrete equations are solved for thermo-elastic problems to obtain temperature distribution in domain. Thereafter, these results acts as load input criterion for elastic discrete equations. Post process of simulation, SIFs at crack tips are calculated using interaction integral approach for few orthotropic composites with preexisted crack. © 2019 Elsevier Ltd. All rights reserved.
