Abstract:

A computational study was performed to compare the current finite element analysis model of Roma Plastilina No. 1 clay based on Lagrangian clay element formulation with arbitrary Lagrangian–Eulerian (ALE) element formulation and with alternative ALE material models. The objective of the study was to assess the feasibility of the ALE modeling technique for this application and the accuracy of the various material models combined with the ALE modeling approach.
