The most commonly used objective function in structural optimization is weight minimization. Nodal displacements, compliance, the first natural frequency of vibration, critical load factor concerning global stability, and others can also be considered additional functions. This paper aims to propose seven innovative many-objective problems (MOSOPs) applied 25-, 56-, 72-, 120-, 582-bar trusses, not yet presented literature, which main objectives, addition structure’s weight, refer structures’...
Abstract This paper presents our effort to addressing fluid–structure interaction (FSI) problems by means of computational mechanics. A stabilized finite element formulation is used solve the incompressible Navier–Stokes equations written in primitive variables. The structure modelled using rigid‐body dynamic solved a Runge–Kutta method. distinctive feature approach combination large eddy simulation (LES)—based on implicit turbulence modelling—with time–space adaptive techniques arbitrary...
Aspects concerning resonance and global stability of a wind turbine blade must be carefully considered in its optimal design. In this paper, composite with an external geometry based on the NREL 5 MW model was subjected to multi-objective structural optimization considering these aspects. Four problems are formulated mass, maximum tip displacement, natural frequencies vibration, critical load factor as objective functions. The design variables number plies, material, fiber orientation....
Formulations of structural optimization problems are proposed in this paper to automatically find the best grouping columns 3D steel buildings. In these formulations, conflicting objective functions, minimized simultaneously, weight structure and number different groups columns. other words, smaller columns, greater structure, groups, structure’s weight. The design variables bracing system configuration, column cross-section orientation, assigned W-shaped profile indices for beams, braces....
Hybrid-electric aircraft have been studied in recent years, aiming to contribute reducing pollutant aviation emissions. Analysis and design of hybrid power-trains able substitute conventional systems actual given rise several approach strategies, combined with simulation tools. Since the hybrid-electric power-train is composed subsystems that exhibit non-linear behavior their energy conversion, calculating its basic characteristics optimally original system a highly complex task. Employing...
The objective of this article is to present the results obtained in a study on interaction between behavior structure and foundation settlements verify influence normal load distribution columns. In mechanism, known as soil (SSI), building constructed, transfer loads occurs from columns which tend settle more those that less. was conducted had its monitored beginning construction. For purpose, linear tridimensional numerical model constructed analysis performed, using finite elements method....
During the construction of a building, transfer loads occurs from columns which tend to settle more those that less. This observable fact can be attributed mechanism called static soil-structure interaction (SSI). In order understand this mechanism, is often not considered in designs, an experimental campaign and numerical simulation were carried out on building had its settlements monitored start construction. For purpose, linear tridimensional models constructed for each floor analysis was...
The widespread exploration of drones has generated increasing interest in Micro Aerial Vehicles (MAVs). Furthermore, an application that gained notoriety is the use aerial vehicles for on Mars. Thus, quest efficient aerodynamic profiles these applications been intensified. These types operate a Reynolds number range from 10^4 to 10^5, which significantly smaller than those commonly found conventional low regimes, such as when commercial are adopted. main objective here identify more shapes...
