In order to determine the characteristic feature in the deformation behavior of particulatereinforced composite material, a constitutive equation that takes into account the characteristic length scale has been developed using the strain gradient theory. By means of the plane-strain finite element method with the proposed constitutive equation, a series of simulations of inhomogeneous deformation behavior of composite materials with different volume fractions of reinforcement, particle size and distribution pattern of reinforcement have been performed. As a result, it has been determined that the resistance of composite material to deformation is substantially increased with the refinement of the particle size under constant volume fraction of reinforcement. Furthermore, the regulaization of the distribution pattern which increases the value of the maximum strain gradient in the matrix contributes toward improving the resistance to deformation.
