This paper studies a novel geometry for the in-plane shear test performed with an axial electromechanical testing machine. In order to investigate the influence of the triaxiality rate on the mechanical behavior. different tests will be performed on the studied material: simple tensile tests. large tensile tests and shear tests. https://www.roneverhart.com/Pizzalapio-pyorea-reiallinen-alumiinia-36-120-cm/
