Bending Analysis of Laminated Composite Plates with Arbitrary Boundary Conditions
It is well known that for laminated composite plates a Levy-type solution exists only for cross-ply and antisymmetric angle-ply laminates. Numerous investigators have used the Levy method to solve the governing equations of various equivalent single-layer plate theories. It is the intension of the present study to introduce a method for analytical solutions of laminated composite plates with ar...
متن کاملShape Optimization in Laminated Composite Plates
At this stage a substantial body of literature exists for shape optimization involving isotropic materials. The reader is referred to the articles of Haug [1] and Haftka and Grandhi [2] for overviews of the material. One approach to the problem is analytical. Calculus of variation techniques are employed to derive explicit optimality conditions. Choi and Haug [3], Dems and Mroz [4], and Banichu...
متن کاملexperimental bending analysis of strip sandwich and laminated composite plates
there exist simple theories to predict the strain of sandwich structures under a bending load and specific support conditions. although theoretical predictions are highly effective, but the role of testing in validation of these theories and their progress is undeniable. the main goal of the present paper is to prepare a test instruction in order to minimize the error of data acquisition and th...
متن کاملStructural Optimization of Laminated Plates with Genetic Algorithms
Laminated plate optimization is a combinatorial problem where the objective is to find the optimal sequence of materials from a given set, along with the respective fiber orientation. Due to manufacturing reasons, the size of each ply can only take a discrete number of values and, together with the available materials, results in an integer programming problem. Therefore, an approach based on G...
متن کاملOptimization of Electromagnetic Absorption in Laminated Composite Plates
This paper analyzes an electromagnetic model of radar-absorbing layered structures for several stacking sequences of a woven glass/vinyl ester laminate, foam layers, and resistive sheets. It considers configurations that are either deposited on different backing materials or embedded in a laminated sandwich plate. Through-the-thickness layer dimensions and sheet resistances offering the best si...
