Development of biaxial tensile testing for porous polymer membranes

Porous polymer membranes are typically polymeric materials that consist of many pores and complex network structures. As a result of these features, the membranes sometimes undergo anisotropic elastoplastic deformation. Hence, it is important to investigate the deformation behavior of these material...

In this study, we developed a new biaxial tensile testing machine for porous polymer membranes to evaluate their deformation behavior under biaxial tension and to understand the deformation mechanisms from their microstructure. First, uniaxial tensile tests were conducted to investigate changes in Young's modulus and yield strength for different tensile directions.
