  • JANCAE activity for implementing rubber material to advanced finite element codes and application example

抄録

<p>When conducting numerical analysis on rubber products, it is necessary to select a material model. On the other hand, CAE analysis using an advanced finite element solver has become widely common, but the rubber material model implemented in each advanced finite element solver is not unified. Therefore, the Japan Association for Nonlinear CAE (JANCAE) has started to implement rubber material independent of advanced finite element solvers in its working group activities, and has created a subroutine library "UMMDr". In this report, we first explain the activity contents of this working group. Next, we introduce implement method to advanced finite element solver "LS-DYNA". Finally, we show verification between UMMDr and LS-DYNA built-in Material.</p>
