摘      要：The objective of this research was to determine the mechanical parameter from EVA foam and also investigate its behavior by using Blatz-Ko,Neo-Hookean,Mooney model and experimental *** physical characteristic of EVA foam was also evaluated by scanning electron microscopy(SEM).The results show that Blatz-Ko and Neo-Hookean model can fit the curve at 5%and 8%strain,*** Mooney model can fit the curve at 50%*** modulus of rigidity evaluated from Mooney model is 0.0814±0.0027 *** structure of EVA foam from SEM image shows that EVA structure is a closed cell with homogeneous porous *** the result,it is found that Mooney model can adjust the data better than other *** model can be applied for mechanical response prediction of EVA foam and also for reference value in engineering application.
