How to determine the ""normalized volumetric compliance" when define visoelastic material behavior?

08 August 2016 1 10K Report

I am going to define the visoelastic of materials with Volumetric Test Data,but the parameter needed in abaqus make me confused, who can tell me about how to calculate the normalized volumetric compliance and Jk or Kr, Thanks very much .
