On the determination of modified cam clay model parameters

Dipika Devi

Numerical analysis of any boundary value problems requires a constitutive model to be used. Depending on the type of the problem to be solved and the material characteristics involved in the analysis, the constitutive model to be used in the analysis should be selected properly, so that the results close to the real behavior of the analyzed problems. Again, numerical prediction of any constitutive model depends highly on the correct selection of the model parameters. These model parameters for a given material are generally determined from different experimental data. Therefore, selection of a constitutive model and determination of its parameters for a given material are must in any numerical analysis  It can be seen from literature that modified cam clay model is mostly used in numerical analysis of geomechanics problems requiring realistic soil models. To use this model for analyzing any problems in a given soil, the different model parameters for that soil are to be determined carefully. In the present study, selection and determination of the modified cam clay model parameters for some soils is done. The soils used in the study are collected from inside the NERIST campus, which is situated in Papumpare district of Arunachal Pradesh.;
