In the current paper we present a fast, reliable technique for simulating wave propagation in
complex structures made of heterogeneous materials. The proposed approach, the spectral …

We present a numerical homogenization approach for hybrid metal foams, ie foams that are
electrocoated to improve their mechanical properties. Based on the finite cell method, a …

Recent multiresolution topology optimization (MTO) approaches involve dividing finite
elements into several density cells (voxels), thereby allowing a finer design description …
