摘要: In this paper, a thermal-mechanical augmented finite-element method (TM-AFEM) has been proposed, implemented and validated for steady-state transient, coupled analyses of complex materials with explicit consideration arbitrary evolving cracks. The permits the derivation explicit, fully condensed equilibrium equations which are mathematical exactness in piece-wise linear sense. 4-node quadrilateral two-dimensional (2D) element tetrahedron three-dimensional (3D) element. It demonstrated, through several numerical examples that new TM-AFEM can provide significantly improved accuracy efficiency when dealing crack propagation problems 2D 3D solids under loading conditions. This article is part themed issue 'Multiscale modelling structural integrity composite materials'.
