Abstract
A mathematically well defined criterion is developed to realize, with the help of finite element and optimization methods, the shape optimization of biaxial cruciform specimens for anisotropic elastic materials. Numerical simulations of off-axes tests on an orthotropic Cu-Zn alloy reveal the decisive superiority of the optimized specimen compared with specimen designs proposed in the literature, as well as the paramount importance of an original off-axes testing device conceived for the proper performance of biaxial off-axes tests. A series of biaxial tests on aluminium alloy indicates the abundance of results which can be obtained from a single optimized cruciform specimen, when the mechanical concept and the servocontrol system of a direct biaxial testing machine are adequately devised.
