Equivalent elastic modulus prediction method for transition region of composite structure of two-phase material

The invention discloses an equivalent elastic modulus prediction method for a transition region of a composite structure of a two-phase material, and belongs to the technical field of material performance prediction. According to the method, a micro-mechanical model for predicting equivalent mechanical property of the transition region is established for the transition region of the composite structure of the two-phase material. A thought that the transition region is composed of segmented uniform dielectric layers and particles are mingled with the composite material in micro-mechanicals is introduced in the model, one material is supposed to be a basic phase, and the other material is supposed to be a constituent phase. Then the equivalent elastic modulus prediction method for the transition region is established through a Mori-Tanaka mean field theory for equivalent mechanical attribute prediction in micro-mechanicals. Therefore, an explicit description form of an equivalent mechanical attribute of each un
