Abstract: The Finite Element method is used to make a convergence study and a parametric study for T- tubular joints under in-plane bending moment. The tubular joint is modeled using a 9 noded, Hetrosis, thick shell element. ln order to simulate the actual behavior of the joint, material and geometrical nonlinearities are considered. The members material formed the tubular joint is assumed to be isotropic, elastic-perfectly plastic obeying Von Misses yield criterion, while a total Lagrangian formulation is used to include the effects of large deformation in the problem. The present study shows that the large deformation has a slight effect in strengthening or weakening the joint under in-plane bending moment. It is also concluded that the chord legth has a regardless effect on the ultimate in-plane bending moment behaviour of the joint.

Abstract: Skirt is a part of air cushion vehicle (ACV) which plays a substantial role to create an over-pressure (above atmospheric pressure) between floor of structure and water surface. This pressure lifts main hull structure in order to travel through different surfaces as sea-surface, mud, and land. A suitable materials of ACV’s skirt is necessary to survive ACV before high-pressure bubble in under-water explosion (UNDEX). This paper builds up a technique which connects together the finite element method (FEM) and Coupled Eulerian- Langrangian (CEL) strategy to simulate and modify predicted data whereas the high-pressure bubble impact air cushion vehicle (ACV). To prove the promising results of this technique, authors conducted two feature studies from Klaseboer et al. (2005) [1] and A. M. Zhang again in Abaqus software [2], which showed the precision of the calculation model and method. With the similar above model, finite element simulation of the ACV’s skirt model subjected to high-pressu
