The work provides an exhaustive comparison of some representative families topology optimization methods for 3D structural optimization, such as the Solid Isotropic Material with Penalization (SIMP), Level-set, Bidirectional Evolutionary Structural Optimization (BESO), and Variational Topology (VARTOP) methods. main differences similarities these approaches are then highlighted from algorithmic...

This article aims to propose an approach the stress-based topology optimization of continuous elastic bi-dimensional structures subjected design-dependent self-weight loads using Bi-directional Evolutionary Structural Optimization (BESO) method. Topology is developed through minimization P-norm von Mises stress while satisfying a volume constraint. To implement algorithm, consistent sensitivity...

Glued-Laminated Timber (GLULAM) is a widely-used building material, popular for its strength, durability, and sustainability. It created by bonding together layers of wood, making it common choice civil structures. In this study, Bi-directional Evolutionary Structural Optimization (BESO) proposed to improve the performance GLULAM By positioning steel bars within structure, objective increase st...

We investigate the use of combining SIMP topology optimization and phase field method to fracture for maximizing resistance a structure composed two materials. The problem is formulated with respect external work under constraint inclusion volume fraction. performance convergence proposed algorithm are investigated. It shown that can be improved as compared several guess designs same fraction r...

Because of descriptive nonlinearity and computational inefficiency, topology optimization with fatigue life under aperiodic loads has developed slowly. A constraint method based on bidirectional evolutionary structural (BESO) an load is proposed in this paper. In view the severe damage respect to design variables, effective stress cycles are extracted through transient dynamic analysis. Based M...

A smooth bidirectional evolutionary structural optimization (SBESO), as a version of SESO is proposed to solve the topological vibrating continuum structures for natural frequencies and dynamic compliance under transient load. weighted function introduced regulate mass stiffness matrix an element, which has inefficient element gradually removed from design domain if it were undergoing damage. A...
