State-of-the-art computational methods

 

Our laboratory has spent a lot of effort for the construction of state-of-the-art numerical methods for the efficient simulation of static and dynamic phenomena in composite structures. The Finite Wavelet Domain (FWD) method has been recently developed and pioneering wavelet-based elements using Daubechies family of wavelets as basis functions have been constructed. Moreover the Time Domain Spectral Finite Element (TDSFE) method has been employed and efficient multi-nodal spectral elements have been constructed.
