This paper presents a numerical analysis of indented pipes based on the Finite Element (FE) within the framework of COMSOL Multiphysics. Numerical models using two-dimensional solid plane strain elements are evaluated. Geometric nonlinear analysis, nonlinear isotropic hardening material and contact were also incorporated into the models. The numerical models are calibrated by using an analytical model of the Scientific Community.
