Tensile strength of aluminium for different slenderness using finite element method (FEM)

Abstract

For many years, strength of material have been a topic of analysis but the demand to have further knowledge about this topic is remains important especially for aluminium alloy. Increasing usage of aluminium alloy nowadays has made the research about aluminium become more important. This research is about tensile strength of aluminium plate for different slenderness. Aluminium alloy 5083-Hl 16 is used in this investigation since it is the common aluminium used in marine structures. This research involving three different size of tensile coupon which gives different slenderness ratio. The method used to investigate tensile strength of aluminium is by simulation program, ABAQUS. Using ABAQUS software, model can be developed using finite element method to predict the tensile strength. The data of tensile stress is compared with the experimental data from previous research to know the reliability of simulation program. In addition, this research also studies about damage and failure of aluminium alloy. Comparison is made between the prediction with and without damage criteria.
