Abstract In this study, two/three-dimensional computational grains are developed for micromechanical modeling of heterogeneous materials with nanoscale inhomogeneities, considering the interface stress effect. Two types of computational grains are developed, depending on the types of inhomogeneity in each element. Each computational grain can include alternatively a spherical void or a spherical elastic inclusion. In these computational grains, an inter-element compatible displacement field is assumed along the element outer-boundary, and interior displacement fields in the matrix as well as in the inclusion are independently assumed as T-Trefftz trial functions. For planar problems, complex potentials are used to derive the Trefftz trial displacement… More >
