Prony shear relaxation ansys
WebThe Prony coefficients are added directly to the ANSYS engineering data component in addition to the elastic properties. The addition of viscoelastic behavior in the material properties of the internal liner adds an extra degree of complexity to the material model. On the other hand, this new behavior excludes the possibility of including ... Webalgorithm is employed. The measured data includes ramp loading, relaxation, and unloading stress-strain data. The resulting Prony series, which captures strain rate loading and …
