Abstract

In this paper, the full-field strain and strain concentration factor around the hole of PTFE membrane under uniaxial biaxial tension are studied based on digital image speckle (DIC) technique and finite element calculation.Through the load-strain curve of porous membrane during tension, three stages of properties of membrane during biaxial tension are obtained: elastic stage, plastic stage and failure stage.The relationship between the maximum strain around the pore, the ultimate bearing capacity of the membrane and the pore size is obtained. The relationship between the strain concentration factor at the pore edge and the pore size is obtained.The results show that the larger the pore size, the more obvious the strain concentration around the pore and the smaller the ultimate load it can bear, and the greater the strain concentration coefficient around the pore, the more easily the membrane is damaged.
