Wavelet Spectral Finite Elements for Wave Propagation in Composite Plates
The principal objectives of the research are to develop and experimentally validate a predictive modeling capability for simulation of wave propagation in 2-D composite plates. During this reporting period, the Wavelet Spectral Finite Element (WSFE) model for composite plates (developed by Prof. Gopalakrishnan at IISc Bangalore) was implemented at Clarkson. Composite plates were fabricated usin...
متن کاملA New Numerical Procedure for Determination of Effective Elastic Constants in Unidirectional Composite Plates
In this paper a composite plate with similar unidirectional fibers is considered. Assuming orthotropic structure, theory of elasticity is used for investigating the stress concentration. Also, complex variable functions are utilized for solving the plane stress problems. Then the effective characteristics of this plate are studied numerically by using ANSYS software. In this research a volume e...
متن کاملWave Propagation Scattering Due to Defects on Thin Composite Plates
Engineering structures which are based on laminated composites have a high probability of unexpected damage developing during service. The damaged formations must be monitored from the beginning before they head towards structural failure which could result in substantial damage. This leads to the necessity of a structural health monitoring (SHM) system to be installed during the construction o...
متن کاملEffective wave propagation in a prestressed nonlinear elastic composite bar
The problem of determining the effective incremental response of nonlinearly elastic composite materials given some initial prestress is of interest in numerous application areas. In particular, the case when small-amplitude elastic waves pass through a prestressed inhomogeneous structure is of great importance. Of specific interest is how the initial finite deformation affects the microstructu...
متن کاملBuckling and vibration analysis of angle -ply symmetric laminated composite plates with fully elastic boundaries
The main focus of this paper is on efficiency analysis of two kinds of approximating functions (characteristic orthogonal polynomials and characteristic beam functions) that have been applied in the Rayleigh-Ritz method to determine the non-dimensional buckling and frequency parameters of an angle ply symmetric laminated composite plate with fully elastic boundaries. It has been observed that o...
