Numerical Simulation of Heterogeneous Hyperelastic Model with RKDG

In the present work, the thickness distribution in a plug-assisted thermoforming process is investigated using finite element (FE) simulations. Numerical simulations have been performed with the FE code ABAQUS/Explicit. The contact between sheet and tools is considered as isothermal. Moreover, the coefficient of friction between plug and sheet is assumed constant. The behavior of the material is described by three hyperelastic laws available in the FE code. The comparison between experimental and FE results highlights that the neglected thermal effects (conduction and convection) and the thermal dependence of coefficient of friction should be considered. For future work, we propose an elasto-viscoplastic model which appears to better describe the behavior of the material than a hyperelastic model.

Loading Tests

This paper shows the results of the leakage tests and the large deformation analysis of a full-scale glovebox window to establish the capacity of the containment of the MOX fuel manufacturing glovebox during an earthquake. In leakage tests, the stainless steel container installed on the reverse of the glovebox window was pressurized with a halogen-air mixture after deformation was applied to the upper part of window frame using 6 micro handy jacks, and to the four glove-ports using electrical actuators. A numerical model for the rubber seal was obtained with biaxial loading tests of chloroprene sheet specimens. Tensile loading tests of acrylic resin specimens were conducted to measure the material modulus. The FEM code ABAQUS was applied to the numerical simulation and the user-subroutine function for the hyperelastic model was used to predict the deformation of the rubber seal. These tests demonstrated that a glovebox window constructed with a rubber seal and a resin panel shows no leakage larger than 0.1 vol%/h with large static deformation. The results of the numerical simulation showed that the rubber seal resolved the effects of deformation of a window panel on the containment barrier, and that two lips of the rubber seal play a key role on the containment of the glovebox.
