Abstract
In this study, homogenization finite element analysis of compression tests for rubber specimens with periodic hole structure to investigate the effect of microstructure on mechanical properties of foamed rubber. The rubber specimens were made by natural rubber and periodical holes were processed mechanically. The diameter to hole and distance of holes were supposed as constant to present relative density of rubber form material. For homogenization methods, biaxial loading tests of natural rubber were conducted to evaluate elastic potential function of hyperelastic material. In small strain region, numerical results of homogenized analysis showed good agrement with loading tests results. From the experimental and simulates results, possibility of homogenization analysis to rubber form material which have periodical microstructures were confirmed.
