WebHyperelastic material models are regularly used to represent the large deformation behavior of materials with FEA.They are commonly used to model mechanical behaviors of unfilled/filled elastomers. WebAs explained in the early paragraph, magnetorheological materials with hyperelastic matrix (MREs) belong to materials that behave as a solid when they are experiencing rapid deformation. Meanwhile, the materials undergo flowing as liquid materials when they are subjected to the very slow deformation.
