Topology optimization of nonlinear mechanical metamaterials using a Fast-Fourier-Transformation-based solver
Materials that respond to a stimulus in a well-defined and nonlinear manner are an important step towards long-lived, trainable material systems. My research focuses on engineering metamaterials with a nonlinear macroscopic mechanical behaviour. To achieve this, I will perform topology optimizations on a periodically repeated unit cell of the metamaterial using an efficient solver that is based on an algorithm called the Fast-Fourier-Transform (FFT).
