A generalized plane strain meshless local Petrov–Galerkin method for the micromechanics of thermomechanical loading of composites

Isa Ahmadi and Mohamad Aghdam

Vol. 5 (2010), No. 4, 549–566

A generalized plane strain micromechanical model is developed to predict the behavior of a unidirectional fiber-reinforced composite subjected to combined thermal and mechanical loads. An appropriate meshless local Petrov–Galerkin formulation is presented for the solution of the governing partial differential equations of the problem. To reduce computation time, a unit step function is employed as test function. A direct method is presented for enforcement of the continuity of displacement and traction at the fiber-matrix interface to model the fully bonded interface. Results of this study revealed that the model provides highly accurate predictions with relatively small number of nodes. Numerical results for glass/epoxy and SiC/Ti composites subjected to thermomechanical loading show that predictions for both local and global responses of the composites are in good agreement with results of theoretical, experimental and finite element methods.
