FEM Model of Structure for Weightlifting in CrossFit in Terms of Material Parameters

Popis výsledku v původním jazyce

The paper deals with problem of construction for Weightlifting in CrossFit from point of view of material parameters. The specific structure has to withstand repeated impact loads. Therefore it is also necessary to deal with stress-strain states. Because of behavior of impact loading and elastomers used in FEM computational model, explicit integration scheme and material constitutive models have to be included. To use constitutive models, material parameters have to be well known. In this paper, the 2-parameter Mooney-Rivlin model is used. That is the reason, why this article is focused on obtaining material parameters of elastomers for FEM computational modeling based on their hardness. Mooney-Rivlin parameters can be determined on the basis of the Shore A hardness. There are exist equations which can be used conversion of the mentioned hardness to material parameters of elastomers. The procedure is such that the Shore A hardness is converted to the elastic or shear modulus and then Mooney-Rivlin material parameters are determined from the modulus. But these equations can lead to different results for the same hardness. In this paper, these results are comparison. For create a 3D model the SolidWorks software is used and for FEM analyses well-known the ANSYS Workbench software is used.
