Wavelet Spectral Finite Elements for Wave Propagation in Composite Plates with Damages - Years 3-4

Abstract

The objective of the proposed efforts -Formulated Wavelet Spectral element for a healthy composite plates and used the formulated spectral element to obtain all the lamb wave modes. Validated the element with the conventional finite elements -Formulated the wavelet spectral element for a plate with transverse cracks and validated this damaged element with conventional finite elements -Development Wavelet Spectral elements for a composite plates with arbitrarily oriented cracks -Development Laplace Transform based Spectral element formulation for plates with cracks
