Finite Element-Based Characterization of Viscoelastic Materials
The objective of this study is to acquire a full characterization of a hyper-elastic material. The process is realized by performing a Dynamic Mechanical Analysis (DMA) with a viscoelastic material, which is extended by image processing algorithms in order to measure the changing distance of two dots in the direction of contraction. Due to the non-linear behavior of the material, the model cannot be expressed by Neo-Hookean model precisely, so in order to overcome this problem, hyper-elastic material models are introduced. Hyper-elasticity provides a means of modelling the stress- strain behavior of such materials. Using the Weak Form PDE interface of COMSOL Multiphysics® software, three mathematical models are developed, where the strain- energy density function depends on different hyper-elastic constitutive equations, including the painted dots which are placed by using domain point probes.
