Abstract
This paper investigates different lattice arrangements of perforated hollow sphere structure (PHSS) on their mechanical properties. For this new kind of hollow sphere structure, the outer sphere shells are perforated by several holes. This will open the inner sphere volume and embed with the epoxy-based adhesives to form syntactic metal foam. The numerical models of PHSS are developed by using Femap software for different lattice arrangements like body-centred cubic (BCC), face-centred cubic (FCC) and hexagonal. The simulation is conducted in MSC Marc software by applying quasi-static compression in order to determine the effective Young’s modulus and Poisson’s ratio values against the average density. Through this paper, it is found that the difference in lattice arrangements do not give significant effect on the Young’s modulus. However, in the case of size of perforation hole diameter, we can see the variation of Young’s modulus and Poisson’s ratio are significant. The results then are compared to the previous study of primitive cubic (PC).
