The present work addresses the problem of maximizing a structure load-bearing capacity subject to given material strength properties and volume constraint. This can be viewed as an extension limit analysis problems which consist in finding maximum load for fixed geometry. We show that it is also closely linked minimizing total under constraint carrying loading. Formulating these topology optimi...

Abstract By using topology optimization, we consider the problem of designing a passive acoustic device that allows for one-way flow sound waves; such is often colloquially referred to as an diode. The Helmholtz equation used model time harmonic linear wave propagation together with Dirichlet-to-Neumann (DtN) type boundary condition, and finite element method discretization. objective this stud...

A novel approach for the solution of wind farm layout optimization problem is presented. The annual energy production maximized with constraints on minimum and maximum number turbines placed, spacing between turbines. proposed relies a density-based topology method, where continuous density variables varying zero one are assigned to each potential turbine location. exists if its associated vari...

The development of technologies for the additive manufacturing, in particular metallic materials, is offering possibility producing parts with complex geometries. This opens up to using topological optimization methods design electromagnetic devices. Hence, a wide variety approaches, originally developed solid mechanics, have recently become attractive also field electromagnetics. general disti...

1. Abstract In this research, a reliability based topology optimization (RBTO) for structural design methodology using the Hybrid Cellular Automata (HCA) method is proposed. More specifically, a decoupled reliability based design optimization (RBDO) approach is utilized, so that the topology optimization is separate from the reliability analysis. In this paper, a maximum allowable displacement ...
