Abstract

The interaction between experimental investigations and the nonlinear elasto-plastic finite element analysis of deeply dented pipes is presented. Finite element modeling aided in defining the length, diameter and thickness of the steel pipes used in the experiments, by subjecting the proposed FEA pipe models to deep denting using the displacement control mode and calculating the forces required to close the gaps. In this way, a pipe is chosen that does not exceed the capacity of the MTS axial-torsional equipment, used in the experiments. Computer control is used to run the MTS, collect and store all the signals received from the signal conditioners. The validity of nonlinear, iterative finit
