Abstract
This paper presents a benchmark study on grounding simulations. The objective was to compare key parameters in modelling techniques and assump-tions for finite element (FE) analysis. Five contributors participated in the bench-mark study by performing numerical simulations, and results were compared with available results from experimental tests. Good agreement between experi-mental tests and numerical simulations was achieved which illustrates that non-linear finite element analysis can be used to estimate the damage extent in grounding scenarios. In addition, a sensitivity study was performed in order to investigate the effect of varying different parameters such as friction coefficient and failure strain values. For the numerical results following the guideline DNV GL-RP-C208 [5], a calibration case for mean failure strain was used in order to simulate real experimental tests (with measured yield and ultimate strength), and good agreement was achieved
