Abstract

Lightweight material is more likely to be used in transportation industries such as aerospace, automobile, shipping and military since it can reduce the usage of energy and costs beside conserve the resources. Therefore, lattice structure that made up from ABS plastic was introduced and investigated in this project. The investigation will be based on development of numerical methods in the means of finite element (FE) methods in order to determine the behaviour of the lattice structure. Therefore, this project will design and develop FE model of lattice structure with different aspect ratio. In addition, the result from analysis using the software will then compared with experiment that will be obtained from another project. The designing phase of the lattice structure model is by using SolidWorks software with different aspect ratio; 0.18, 0.23 and 0.28 meanwhile ANSYS software is used for the analysis of the model under compression loadings. As expected, bigger aspect ratio gives higher compressive yield force. Furthermore, there are huge differences between the analysis and experiment data which is then discussed in the discussion chapter. Some recommendation is done in order to improve the result of this study in the future.
