Finite element analysis about effects of stiffness distribution on stresses and elastic strain energy near the triple junction in a tricrystal

A three-dimensional anisotropic finite element analysis was performed to in vestigate stresses and elastic strain energy in the models that were taken from a copper tricrystal. The purpose was to determine how the stiffness di stribution affected the stress-state near the triple junction. The finite e lement results show that stresses and elastic strain energy density near th e triple junction depend greatly on the stiffness distribution in tricrysta l models. Because the bending and twisting deformation occurs when the tric rystal is uniaxially loaded, stresses at surfaces are significantly differe nt from the interior stresses near triple junction.
