An Experimental and Numerical Investigation on Vulcanized Fiber
As the automotive industry and its companies start to look for sustainability, materials made of natural fibers receive a growing interest. In the present work, the mechanical properties of a vulcanized fiber material were investigated to understand the orthotropic and rate-dependent material behavior and make it more predictable and thus practicable. *MAT_PAPER was used to represent the anisotropic elastic-plastic behavior of the material for crash and impact simulations. To confirm numerical results from explicit FEM calculations, a user material subroutine comparable to *MAT_PAPER was utilized. Therefore, it was possible to perform implicit calculations of the conducted validation experiments which were performed at low strain rates.
