Simulation of Consolidated Undrained (CU) Triaxial Test Abaqus

In first step the confining pressure of 210 kPa is applied at the top surface and the right side of the soil

Second step is the shearing step with duration of 100 seconds

This example is modeled on undrained conditions, so the loading rate must be fast , and a short time period should be considered for it

The top and bottom surfaces of the soil are impervious in consolidated undrained tri-axial test model , so that the possibility of drainage from these two surfaces would not be provided
