Modelling and Structural Simulation of Thin-Wall Structure

This paper performs a non-linear analysis of a thin-walled structure. This simulation uses the finite element method to calculate actual conditions in a matrix calculation that is visualized. In the finite element method for numerical solutions of elliptic partial differential equations, the stiffness matrix represents the system of linear equations that must be solved to ensure approximate solutions to the differential equations. A plate will be given different stiffener shapes with the same pressure value. There will be two boundary conditions applied at this thin-walled structure, displacement and fixed support will be applied at the side of the plate. The output obtained from this simulation are von mises stress, total deformation, elastic strain and strain energy. Each model of thin-walled structure will have various values of this output. And the outcome of this research will be helpful as the selected design of the best stiffener able to improve the performance of thin-walled structure for design and manufacture of marine and land transportation.
