Simple Shear (SS) test is considered to simulate the in-situ stress conditions more accurately than any other testing system. Undrained Cyclic Simple Shear test is extensively performed to evaluate the cyclic shear strength and liquefaction potential of soil. In this study, the numerical modeling of the SS testing was undertaken using a finite element method (FEM) in the Opensees (Open System for Earthquake Engineering Simulation). The study showed that FEM simulation can efficiently capture the cyclic shear behavior and the excess pore water pressure development. The analysis results were also compared with the laboratory measurements and shown to satisfactorily match the measurements.
