Abstract
This paper presents an improved rail shear method of ASTM D 4255/D4255M and the design procedure of new fixture for low cyclic shear loading. This fixture is designated to determine mechanical properties of in-plane shear modulus, nonlinear shear stress-strain curves, shear strength and visco-elastoplastic behaviour of fibrous composites under cyclic shear loads. A series of experiments have been carried out using the new rig to determine shear stress-strain response of unidirectional fibre reinforced laminated specimens under various cyclic loading conditions. An FE simulation has been conducted using a commercial code ABAQUS and its user subroutine UMAT to define nonlinear material behaviour as a verification of the accuracy of the new Cyclic Rail Shear Fixture (CRSF).
