Topology optimization of flexoelectric structures

Journal of the Mechanics and Physics of Solids, 2017
Abstract We present a mixed finite element formulation for flexoelectric nanostructures that is coupled with topology optimization to maximize their intrinsic material performance with regards to their energy conversion potential. Using Barium Titanate (BTO) as the model flexoelectric material, we demonstrate the significant enhancement in energy ...

Multi-scale structural topology optimization of free-layer damping structures with damping composite materials

Composite structures, 2019
Damping performance of the free-layer damping structure mainly depends on the damping material layout and its material physical properties. This paper proposes a concurrent topology optimization method for the design of the multi-scale free-layer damping

Fully parallel level set method for large-scale structural topology optimization

Computers & structures, 2019
To realize large-scale or high-resolution structural topology optimization design, a fully parallel parameterized level set method with compactly supported radial basis functions (CSRBFs) is developed based on both the uniform and non-uniform structured ...

Topology optimization in structural mechanics

Bulletin of the Polish Academy of Sciences: Technical Sciences, 2013
Abstract Optimization of structural topology, called briefly: topology optimization, is a relatively new branch of structural optimization. Its aim is to create optimal structures, instead of correcting the dimensions or changing the shapes of initial designs.

On optimal topology of grillage structures

Engineering with Computers, 1986
Two problems of optimum topological design of grillages are discussed: (1) the Equilibrium Linear Programming (ELP), where the analysis model is based only on equilibrium conditions and (2) the Nonlinear Program (NLP), where the ELP formulation is extended to include compatibility conditions. The structural topology is optimized by allowing elimination

Structural Topology Optimization Using a Moving Morphable Component-Based Method Considering Geometrical Nonlinearity

Journal of Mechanical Design, 2018
The moving morphable component (MMC)-based method is a newly developed approach for topology optimization. In the MMC-based method, the design problem is formulated using a set of morphable components, and the optimized structural topologies are obtained

Benchmarking optimization solvers for structural topology optimization

Structural and Multidisciplinary Optimization, 2015
The purpose of this article is to benchmark different optimization solvers when applied to various finite element based structural topology optimization problems. An extensive and representative library of minimum compliance, minimum volume, and mechanism design problem instances for different sizes is developed for this benchmarking.

Evolutionary Structural Topology Optimization for Continuum Structures with Structural Size and Topology Variables

Advances in Structural Engineering, 2007
In this paper, a topology optimization method mixed structures with continuum and discrete elements is proposed. First, based on the stress and displacement formulations of the finite element analysis, a set of stress sensitivity numbers for beam and plane-stress structures are derived.
