Modelling of the Torsional Simple Shear Test with Randomized Tresca Model Properties in Midas GTS NX

Abstract The dynamic properties of soil obtained from the torsional simple shear test (TOSS) are assumed to be uniform throughout specimen. For some exceptional soils, this may hold true, but for most majority soils that we examine, it is obviously not case, and level non-uniformity depends on conditions in which was formed. In paper, discuss a method modelling inherently non-uniform specimens by representing them with elements have an elasto-plastic Tresca material model different (Elastic young modulus yield stresses). combination can simulate nonlinear behaviour found calibrated using TOSS built finite element software Midas GTS NX. Furthermore, influence rigid inclusions studied results show increase stiffness increasing percentage inclusion soil.
