AbstractA good method to directly measure the mechanical properties of a material deformed in compression or torsion is by using the shear punch test. Unlike tensile testing, the shear punch test is not limited by specimen size or shape. However, it is unclear whether there is a limit to the allowable specimen thickness and punch diameter in order to attain (through conversion) tensile properties with reliability and accuracy. According to this study, it was found that the shear punch test was not sensitive to varying specimen thicknesses or punch diameters over a range of 200 to 400 μm and 1.5 to 5 mm, respectively.L’essai de cisaillement par poinconnage constitue une bonne methode de mesure directe des proprietes mecaniques d’un materiau deforme en compression ou en torsion. Contrairement a l’essai de traction, l’essai de cisaillement par poinconnage n’est pas limite par la taille ou la geometrie de l’echantillon. Cependant, la gamme d’epaisseurs de l’echantillon ainsi que de diametres du poincon qui pe...
