Shape optimization of 3-D structures is a challenging task. The newly developed isogeometrical analysis is a more suitable approach, in comparison with other numerical methods, to address the problem. Apart from the ability of defining...

This paper presents an evolutionary structural optimization method based on the displacement of the control points along the boundary of components. Since in high stress working conditions the failure of structures usually ...

Three basic goals are followed in this paper. At first, shape optimal design of structures is considered with emphasis on bending plates using finite element analysis. The developments in this branch of optimization during recent years are described...

A new optimization strategy for eigenfrequency optimization of functionally graded (FG) structures within the framework of isogeometric analysis (IGA) approach is introduced. The proposed methodology which utilizes a ...

A high performance numerical technique in the study of aorto-coronaric bypass anastomoses

configurations using steady Stokes equations is presented. The problem is first expressed as

This paper deals with the convergence of the Evolutionary Structural Optimization (ESO) and the Morphing ESO (MESO) solutions to the optimum in typical beam design problems. The ESO based methods are very simple to implement ...

In this paper we discussed a new numerical technique in the study Aorto-cononaric bypass anastomoses configuration using unsteady Stoke equations. The theory of optimal control based on notations of meaure theory, functional ...

for optimization of two and three-dimensional fillets and notches. A number of key points are defined on the boundary and spline curve are utilized for modeling. The results show that the ESO method can be utilized for shape optimization problems where there exist...
