Abstract
his study investigates homogenized elasto-viscoplastic material modeling of thick perforated plates operating at high temperatures. To this end, homogenized stress-strain relations of a periodic unit cell of thick perforated plates subjected to simple and complex loading are analyzed using a homogenization method of periodic solids. The resulting homogenized stress-strain relations are then simulated using a recently developed elasto-viscoplastic macro-material model based on a general form of quadratic equivalent stress. It is shown that this macro-model successfully represents the macro-anisotropy and macro-volumetric compressibility revealed in the homogenization analysis.
