Estimation of Absorption Performance of Underwater Anechoic Coating by Multilayer Arrangement of Cylindrical Cavity
Abstract: Rubber coatings with inner cavities are often used as underwater anechoic coatings. What is important in improving the underwater absorption performance is to improve the low frequency absorption performance, while satisfying the broadband absorption performance. Generally the homogenous medium can hardly satisfy the broadband absorption performance. In this paper sound absorption coatings with new arrangement of cavities to satisfy both broadband absorption performance and better low frequency absorption performance is …

Numerical Prediction of Shear Modulus of Multi-Layer PUF Cored Sandwich Composites
Abstract: The present numerical investigation was mainly concerned with the evaluation of apparent shear modulus (Gc) of multi-layered polyurethane foam cored sandwich beams using a novel approach through the medium of general purpose program i.e. FEM/ANSYS. Aiming to the goal, three-point bending analysis was performed on sandwich beam models made up of composite face sheets and multi-layer polyurethane foam cores of different layer densities. Finite element models of sandwich beams were …
