The polymers are known to be delicate to hydrostatic pressure. The impact of stress triaxiality proportion on damage and cavitation has been shown in numerous investigations. This article proposes trial examinations to control both the stress triaxiality proportion and the void distribution by microscopic observations of surfaces from tensile tests. For that, the Gurson−Tvergaard−Needleman model was adjusted with the assistance of a finite element code, by utilizing multi-scale trial information. At that point correlation between both numerical and analytical models and experimental data was performed. In addition, a better understanding of the time development of critical parameters, for example, the porosity (volume change) and the stress triaxiality proportion (hydrostatic pressure), was featured.
