Several different elastomer automotive body seals (weatherstrips or weather seals) are analyzed using explicit solver of LS-DYNA. The results are compared with those obtained from non-linear finite element analysis (FEA) solvers widely used for elastomer analysis as well as the experimental results. The nonlinear implicit solver in the current paper refers to Abaqus/Standard. For LS-DYNA, the explicit solver is always employed in the current paper, and the explicit solver refers to LS-DYNA explicit solver except stating explicitly. In summary, LS-DYNA is a good tool for elastomer body seal analysis, especially for seals with complicated contact environment and contact instabilities in applications. The analysis capability of LS- DYNA for elastomer seal can be improved if more appropriate element type and elastomer material model-fitting routine are implemented, especially the element formulations that are suitable for nearly incompressible materials, and the elastomer material model-fitting program for multiple types of testing data. Properly modeled, the LS-DYNA explicit solver can not only be used to simulate the dynamic behavior of the body seal behavior, but also employed for the quasi-static and static behaviors of the seal in reasonable accuracy. It is very effective in solving the problems with contact instability and complicated contact situations.
