An Investigation to Nonlinear Elastic Behavior of Peri-cardium Using Uniaxial Tensile Test
2016
Journal of Stress Analysis
unpublished
In this paper, the nonlinear elastic behavior of pericardium of human, canine, calf and ostrich was studied. For this purpose, the mechanical behavior was investigated from two viewpoints of the Cauchy and Green elastic materials. Firstly, the experimental data were fitted by Cauchy elastic stress equation. The results showed that the response of Cauchy elastic materials was not fitted with the experimental data appropriately. Secondly, the Green elastic materials were studied by assuming
