Abstract

Following a brief background of the PSU-EVP model, the methodology to back-predict the triaxial test data is presented. Based on the back-prediction results, it was concluded that the PSU-EVP model gives good results for most triaxial test data collected at 0.62 MPa/minute and 6.21 MPa/minute; however, PSU-EVP model results at 20.7 MPa/minute had high ARD values. Sensitivity analysis indicated that the HTC back-predictions results are impacted by changes in parameter values, whereas there is minimal effect on the CTC prediction results. Overall, the PSU-EVP model is a fairly good model for predicting the mechanical behavior of powders under dry compression conditions and can be considered as the first step towards the development of more accurate and robust constitutive models for studying the dry powder compression process that takes into account the pore pressures.
