Assume that the material can be described by an elastic spring A in parallel with a Maxwell element B, as shown in Figure 4. Both springs in A and B are hyperelastic. WebAn elastic material is a linear material. This means that stress varies linearly with respect to strain. An elastic material model is accurate for many material models, such as paper, metal, and wood, as long as the deformation is very small. Elastic materials are widely used for finite element analysis and multi flexible body dynamics. prince of bangladesh
