Abstract

The apparatus described herein is designed for the performance of biaxial stretching tests on flat cross-shaped specimens. It can be used with a conventional uniaxial tensile testing machine. The device converts the machine from one that exerts a uniaxial force to one that applies a system of forces in two perpendicular directions. A fixed value of the logarithmic strain ratio ρ = ϵ₂/ϵ₁ can be imposed on the test specimen along these two directions. The fixed ρ-value may be chosen between 0 and 1 according to the geometrical configuration of the device.
