Abstract

The knowledge of a materials ability to safely sustain a load before breaking has been of paramount importance to man ever since structures were first built. The strength of material under tension has long been regarded as one of the most important characteristics required for design, production quality control and life prediction of industrial plant. In recent years advanced composite materials are increasingly used in almost every industrial branch and the components manufactured from these composite materials are usually subjected to complex loading that leads to multi-axial stresses and strain fields. A bi axial testing machine which describes the mechanical behavior of an isotropic sheet material is presented. Mechanisms controlling each other independently impose a tensile stress on a plus shaped cruciform. The sample design has been optimized to reach the highest possible isotropic biaxial strain field. The isotropic nature of fibrous materials has led us to develop an optical method to measure in-plane displacements. The apparatus described herein is designed for the performance of biaxial stretching tests on flat cross-shaped specimen. 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.

Key Words

structures, composite materials, complex loading, multi-axial stress and strain fields.
