This article aims at optimizing laminated composite plates taking into account uncertainties in the structural dimensions. As composites require a global optimization tool, Particle Swarm Optimization (PSO) method is employed. A new Reliability Based Design (RBDO) methodology based on safety factors presented and coupled with PSO. Such are derived from Karush–Kuhn–Tucker optimality conditions of reliability index approach eliminate need for analysis RBDO. The plate weight minimization...
Abstract This article aims at approximating the probability density function (PDF) of optimal point an optimization process. The full characterization PDF optimum is expected to lead more precise failure prevision and increased safety with a cheaper design when compared less accurate approaches such as those which approximate random variables using only their mean variance. polynomial chaos expansion (PCE) employed resulting functional minimized stochastic approximation techniques. Several...
Surrogate models have been widely used for Reliability-Based Design Optimization (RBDO) to solve complex engineering problems. However, the accuracy and efficiency of surrogate-based RBDO largely rely on sample size sampling methods. For this reason, successive methods that update surrogate successively are more promising. Nowadays, several Kriging-based approaches proposed with different techniques. these based Monte Carlo simulations double-loop such most them would be time consuming high...
The vibration of wind turbine towers is relevant to the reliability structure and quality power production. It produces both ultimate loads fatigue threatening structural safety. This paper aims reduce in using an active damper named twin rotor (TRD). A single degree freedom (SDOF) oscillator with TRD used approximate response turbines under a unidirectional gusty loss electrical network. coincidence between gust grid studied involve maximum loading on structure. performance proposed damping...
In this paper, an approach is proposed to conduct reliability analysis on offshore jacket considering corrosion degradation under extreme load cases. Corrosion considered as thickness wastage of the element, which seen time-dependent variables. One probabilistic in literature adopted by using different distribution models. Also, three inspection cases (environmental conditions) are studied. The assessment evaluated Crude Monte Carlo simulation based trained surrogate model. Deep neural...
Abstract Reliability-Based Design Optimization (RBDO) has been developed to design structures that reach the best compromise between cost reduction and reliability by considering uncertainties. This is achieved reformulating initial optimization problem in order introduce probabilistic constraints. Numerical evaluation of these constraints direct approaches turns out be difficult: estimation probability failure implies calculation multidimensional integrals. The integrals often rely on...
The design of reinforced concrete (RC) structures involves several kinds uncertainties, which are usually considered through the partial safety factors prescribed in codes practice. traditional optimization RC uses deterministic information problem. used to consider loading fluctuation and variability material properties. use these leads over-designing structures, as calibrated for a large class structures. In procedure reliability cannot be controlled. For this reason, Reliability-Based...
The models of 3D unsteady coupled fluid-structure systems such as swimming fins are numerically too expensive to be optimized. Designers must therefore make preliminary decisions based on simplified models. In particular, considering 2D cases for optimization is a standard practice. design then needs translated into its counterpart. current work an example problem. objective monofin using optimal flexural stiffness distribution determined in [1]. this study, was represented by rigid bars...
