dc.description.abstractThis thesis discusses a structural optimization method that optimizes a compliant mechanism based on phase field method. Structural shapes are expressed by the phase field function, which defines in the design domain; this function is optimized by solving a time-dependent reaction-diffusion equation. The artificial double well potential function used in the function is derived from sensitivity analysis. The convergence of the compliant mechanism objective functions and the influence of perimeter control on the optimal configurations are illustrated through the numerical examples. A typical inverter problem is used as a benchmark for the compliant mechanism problem optimization method, and apply the method to generate the micro-structure unit cells simulating the behaviour of auxetic materials, i.e. generating a material possessing negative Poisson’s ratio. The upgrade code modified from Takezawa original code which implements the high order FEM to reproduce the new advanced auxetic structure that performs better than its counterparts attained by the original codeen_US
