| Summary: | Abstract This article presents the numerical analysis of architected metal/polymer-based interpenetrating phase composites (IPCs) to study their effective mechanical properties and dynamic behavior using finite element (FE) simulation. In this, we considered four types of Triply periodic minimal surfaces (TPMS) and lattice architectures, including gyroid, primitive, cubic, and octet, to form architected IPCs. The aluminum alloy is used for the TPMS/lattice reinforcing phase, and epoxy as a reinforced phase. The periodic boundary conditions were applied using FE analysis to compute the effective properties, while these properties were utilized to investigate the dynamic analysis of composite structures considering free vibration, wherein actual and homogenized models are compared. Our results reveal that the effective properties of IPCs increase with respect to the volume fraction of respective architectures in conjunction with enhanced natural frequency and less deformation. Moreover, we conducted a comparative study between these newly architected metal/polymer IPCs and conventional composites. |
