Finite Element Stress and Strain Analysis of a Double Shear Creep Specimen

This paper reports on creep stress and strain results obtained by the finite element method (FEM) for a double shear specimen which was recently developed (1). It considers stress redistribution during creep, small changes in specimen geometry during testing and high local stress states at the positions where the specimen is loaded. The results of the present study show that the unconstrained double shear test technique proposed in (1) yields viable results for shear strains of at least up to 0.10. ((1):C.
