Abstract

Finite element simulation of material response behavior under deformation entails identification of constitutive model parameters to truly expound the material behavior. Silicon is found to be hard and brittle and in the absence of experimental data, it is difficult to obtain constitutive model parameters to simulate the material deformation. In this paper numerical simulation of triaxial compression and triaxial tension tests are performed at different confining pressures and a method was adopted to determine the Drucker Prager parameters of silicon. The method involves extracting the data from stress-strain plots of triaxial compression and tension tests to calibrate the ultimate yield surface and then plotting the data in the meridional (p-t) stress plane.
