State-of-the-art computational methods
Our laboratory has spent a lot of effort for the development 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 constructed and pioneering wavelet-based elements using Daubechies scaling functions as basis functions have been created. Moreover, the Time Domain Spectral Finite Element (TDSFE) method has been formed and efficient multi-nodal spectral elements have been employed.
