Abstract
The current study examines the effect of generating optimised topology and shape in use for ‘0–1 (almost void–solid)’ material considering n-order eigenfrequency dependence by using dynamic material topology optimisation. The design method presented in this study aims to determine the layout of material, which finally evaluates optimised topology and shape of structures consisting of a given material, of a specified volume in a design space that maximises natural eigenfrequency with n-order eigenmodes for a given set of boundary conditions. Numerical experiments for generating potential diversity of optimised topology and shape on steel and concrete materials within a given design space verified design dependence on n-order eigenmodes and material dependence on Poisson’s ratio.
