Optimization of Wood Fiber Orientation Angle in Outer Layers of Variable Stiffness Plywood Plate
The new optimization method for fiber orientation angle optimization of symmetrical multilayer plates like plywood is proposed. Optimization method consists of seeking for minimal compliance by choosing appropriate fiber orientation angle in outer layers of flexural plate. The discrete values of fiber orientation angles are used in method. Optimization results of simply supported plate and mult...
متن کاملMulti-objective optimization of buckling load for a laminated composite plate by coupling genetic algorithm and FEM
In this paper, a combination method has been developed by coupling Multi-Objective Genetic Algorithms (MOGA) and Finite Element Method (FEM). This method has been applied for determination of the optimal stacking sequence of laminated composite plate against buckling. The most important parameters in optimization of a laminated composite plate such as, angle, thickness, number, and material of ...
متن کاملModal density and modal distribution in a ribbed plate
Plates reinforced by ribs or joists are common elements in lightweight building structures, as well as in other engineering structures. However, these structures are not well suited for the common simplified prediction models such as Statistical Energy Analysis (SEA) or the European calculation standard EN 12354. There are several reasons for this: One is that the overall vibration field is not...
متن کاملCompliance optimization of a continuum with bimodulus material under multiple load cases
Topology optimization of a continuum with bimodulus material under multiple load cases (MLC) is investigated by using material replacement method. Using traditional methods to solve such a problem will encounter two difficulties for the sake of the stress-dependent behavior of bimodulus material. One is the nonlinear behavior of bimodulus material. The other is the definition of local material ...
متن کاملTopological Derivative-based Topology Optimization of Structures Subject to Multiple Load-cases
The topological derivative measures the sensitivity of a shape functional with respect to an infinitesimal singular domain perturbation, such as the insertion of holes, inclusions or source-terms. The topological derivative has been successfully applied in obtaining the optimal topology for a large class of physics and engineering problems. In this paper the topological derivative is applied in...
