RISShape and topology optimization of mechanical components using the adaptive biological growth method
Different methods were presented for shape and topology optimization. One of them is adaptive biological growth (ABG) method. Through fast computation, higher accuracy and less cost, this method has been used successfully in structural optimization...
Simultaneous shape and topology optimization of shell structures
In this research, Method of Moving Asymptotes (MMA) is utilized for simultaneous shape and topology optimization of shell structures. It is shown that this approach is well matched with the large number of topologyand shape design variables...
A review of homogenization and topology optimization III—topology optimization using optimality criteria
This is the third part of a three paper review of homogenization and topology optimization. In the first two papers the homogenization theory and solution of the equations for different material models to be used in topology optimization...
Maximizing the fundamental eigenfrequency of materially nonlinear structures by topology optimization based on the evolutionary structural optimization
) to improve the ESO procedure. This paper pertains to topology optimization using the BESO method in order to maximize the first eigenfrequency of structures with elasto-plastic bodies. In order to obtain the frequencies of a structure with elasto...
Isogeometric topology optimization of structures by using MMA
The Isogeometric Analysis (IA) method is applied for structural topology optimization instead of the finite element method. For this purpose, the material density is considered as a continuous function throughout the design domain...
Structural topology optimization using ant colony methodology
In this paper Ant Colony Optimization (ACO) and finite element analysis are employed in topology optimization of 2D and 3D structuralmodels. The aim is to find the stiffest structure with a certain amount of material, based on the element’s...
Prevention of undesirable structural elements in three dimensional topology optimization
In this paper, the topological optimization of three-dimensional structures based on optimality criteria and artificial material model is briefly reviewed and prevention of undesirable structural elements is discussed. Prevention of formation...
Derivation of incompatible modes in non-conforming finite elements using hierarchical shape functions
The close relationship between the hierarchical shape functions and the incompatible modes in non-conforming finite elements is investigated and a simple approach is presented to systematically derive the incompatible modes ...
An isogeometrical approach to structural topology optimization by optimality criteria
The Isogeometric Analysis (IA) method is ap-plied for structural topology optimization instead of finite
elements. For this purpose, a control point based Solid Isotropic Material with Penalization (SIMP) method is employed and the material...
