TOPOLOGY OPTIMIZATION OF SPACE STRUCTURES USING ANT COLONY METHOD
In this article, the ant colony method is utilized for topology optimization of space structures. Strain energy of the structure is minimized while the material volume is limited to a certain amount. In other words, the stiffest possible structure is sought when certain given materials are used. In addition, a noise cleaning technique is addressed to prevent undesirable members in optimum topol...
متن کاملData-Driven Stochastic Multiscale Method
Introduction 1 Randomness manifests itself in many aspects of real-world problems, such as initial/boundary conditions, model parameters, measurements, to name a few. 2 Its effect may span many scales and grow with time through nonlinear interactions, which results in dramatic difference compared with that of the deterministic model. 3 A typical scenario occurring frequently in practice is that...
متن کاملStructural Topology Optimization Using Finite Element Based Level Set Method Structural Topology Optimization Using Finite Element Based Level Set Method
A finite element based level set method is proposed for structural topology optimization. Because both the level set equation and the reinitialization equation are advection dominated partial differential equations, the standard Galerkin finite element method may produce oscillating results. In this paper, both equations are solved using a streamline diffusion finite element method (SDFEM). The...
متن کاملGeometric Feature Identification from Topology Optimization Results
1. Abstract Topology optimization yields an overall layout of a structure in the form of discrete density (e.g., SIMP) or continuous boundary geometry (e.g., level-set method). One of important drawbacks, however, is that it leads to a geometry with zigzag boundaries and/or irregular shapes, which is difficult to be interpreted for manufacturability, as well as to be utilized in subsequent appl...
متن کاملTOPOLOGY OPTIMIZATION OF PLANE STRUCTURES USING BINARY LEVEL SET METHOD AND ISOGEOMETRIC ANALYSIS
This paper presents the topology optimization of plane structures using a binary level set (BLS) approach and isogeometric analysis (IGA). In the standard level set method, the domain boundary is descripted as an isocountour of a scalar function of a higher dimensionality. The evolution of this boundary is governed by Hamilton–Jacobi equation. In the BLS method, the interfaces of subdomai...
