Simulation of the mechanical deformation of a feedthrough flange under high pressure conditions

For future LAr calorimeters, a new generation of high-density signal feedthroughs has to be developed that ensures higher granularity and supports a larger number of signal wires. Therefore, 3D designs of different flange configurations were created and mechanical stress simulations were performed to investigate the deflection and the von Mises stress. In this document, the simulation results are presented and discussed.
