DESIGN OF TRANSVERSE BIAXIAL TENSILE TESTS ON CRUCIFORM SPECIMENS

摘要

The particular case of the mechanism of damage known as inter-fiber or matrix failure under transverse tension has already been the object of several micromechanical studies by the authors [1]. These studies have made it possible to understand the initiation of failure at the micromechanical scale as well as its later progress, which leads to the macro-failure of the material. Many of the existing proposals for the prediction of the inter-fiber failure at lamina level are based on the hypothesis that the failure taking place at a plane is governed by the components of the stress vector associated to that plane. This assumption has been revised by Paris et al [2] and Correa et al [3] for the tension dominated matrix failure by means of singlefiber Boundary Element models subjected to biaxial loading.
