Abstract [en]

A Finite Element Analysis of a load test of the LAS-937 adapter has been made to check if there is any risk that the aluminuim in the upper interface of the adapter yields. The analysis was done in ABAQUS CAE. The reason for doing the analysis is that the adapter was measured to be oval after the load-test. Several different analysises were run to check how sensitive the model was to a higher load or lower yield strength in the alumium. It was found that the resulting stresses in the FE-model interface is not high enough to explain the ovality of the the interface. Even with the higher load or lower yield strength properties the deformations in the FE-model were not as high as the measured ovality.
