FEA of Hyperelastic structures: A Case From the Submarine Design

The paper deals with FEA of seals made of a hyperelastic material. The seals are used in a novel design of a tourist submarine and undergo large deformations and strains. Thus, the analysis includes geometrical and material nonlinearity, finite strains and contact conditions. The whole process of analysis from selecting a suitable set of experiments used to calibrate the hyperelastic material model to determining mesh characteristics and interpreting the results is presented. It is shown that the required number of experiments can be minimised by a simple comparison of deformation gradient tensors of the experiments and the problem at hand.
