Abstract :
[en] An experimental testing equipment for sheet samples is built in order to identify
material parameters ofcomplex phenomenological constitutive laws. This equipment consists
in a bi-axial test machine able to perform plane strain and simple shear tests separately or
simultaneously and a Miyauchi simple shear test device. An optical extensometer is used to
identify the strain field. The article is focused on the validation of the results of this new
equipment by comparing with results obtained by finite elements (FE) simulations of already
identified materials. The results are satisfactory and the bases for further material
identification are established.
