- Numerical Simulation Considering Volume Change in Plastic Behavior of ABS Polymer
抄録
<p>It is known that the dynamic behavior of polymers depends greatly on not only the strain rates but also the hydrostatic pressure, and the volume change is caused during plastic deformation. It is desirable to apply material constitutive model considering these mechanical properties in numerical simulation for polymers. Therefore, we developed a new constitutive model for polymers and implemented using the user-subroutine of the impact analysis code LS-DYNA. On the other hand, the plastic Poisson’s ratio during plastic deformation of ABS polymer was measured by Mimura et al.</p><p>In this study, we focused on the volume change during plastic deformation of ABS polymer, and performed numerical simulation considered Poisson’s effect during the plastic deformation using LS-DYNA to verify the validity of this constitutive model and material parameters.</p>
