| Outline of Final Research Achievements |
In the present study, the quantitative evaluation and theoretical modeling of the deformation behavior of the plastic foam were performed to understand the mechanical property characterized by the microscopic structure and deformation of the material. The nonuniform deformation and volume change during inelastic strain range were evaluated using the digital image correlation method. Furthermore, the effect of the microscopic scale on the macroscopic nonuniform deformation of plastic foam is investigated using the second-order homogenization method. Experimental and numerical evaluation of the nonuniform deformation and volume change during inelastic deformation of plastic foam become enabled using the proposed methods in this study.
