Analysis of the interaction within a rectangular array of rectangular inclusions using a new hybrid finite element method

This paper deals with the interaction problem of a rectangular array of rectangular inclusions under longitudinal tension. A novel ad hoc hybrid finite element method is applied to a rectangular cell containing single or multiple inclusions. Generalized stress intensity factors at the corners of inclusions are systematically calculated with varying the material type, shape and arrangement of rectangular inclusions. Present numerical solutions are compared with existing results. The present method is found to be yield rapidly converging numerical solutions with high accuracy.
