The losipescu in-plane shear test: validation on an isotropic material
The purpose of this paper is to compare the value of the shear modulus of an isotropic material (PMMA) obtained from both tensile and losipescu shear tests. A finite-element model is introduced to account for a nonuniform stress distribution in the losipescu coupon. A correction accounting for nonuniform strain values over the strain-gage section is also introduced. Rigorous statistical data processing leads to an estimation of the error between the moduli obtained by the two tests. Some points relevant to the losipescu test are reviewed, particularly concerning the sample preparation. Provided that a careful procedure is followed, excellent agreement is achieved between the shear moduli measured by the two methods

Abstract
The purpose of this paper is to compare the value of the shear modulus of an isotropic material (PMMA) obtained from both tensile and losipescu shear tests. A finite-element model is introduced to account for a nonuniform stress distribution in the losipescu coupon. A correction accounting for nonuniform strain values over the strain-gage section is also introduced. Rigorous statistical data processing leads to an estimation of the error between the moduli obtained by the two tests. Some points relevant to the losipescu test are reviewed, particularly concerning the sample preparation. Provided that a careful procedure is followed, excellent agreement is achieved between the shear moduli measured by the two methods
