Stiffness minimisation of graded microstructural configurations using asymptotic analysis and machine learning
Chuang Ma, Dingchuan Xue, Shaoshuai Li +3
The article is aimed to address a mutually boosting use of asymptotic analysis and machine learning, for fast stiffness design of configurations infilled with smoothly-varying grad…
Optimisation of spatially varying orthotropic porous structures based on conformal mapping
Shaoshuai Li, Yichao Zhu, Xu Guo
In this article, a compliance minimisation scheme for designing spatially varying orthotropic porous structures is proposed. With the utilisation of conformal mapping, the porous s…
Surrogate representation of sink strengths and the long-term role of crystalline interfaces in the development of irradiation-induced bubbles
Jing Luo, Yong Xin, Zhengcheng Zhou +2
The present article addresses an early-stage attempt on replacing the analyticity-based sink strength terms in rate equations by surrogate models of machine learning representation…
Generation of smoothly-varying infill configurations from a continuous menu of cell patterns and the asymptotic analysis of its mechanical behaviour
Dingchuan Xue, Yichao Zhu, Xu Guo
We here introduce a novel scheme for generating smoothly-varying infill graded microstructural (IGM) configurations from a given menu of generating cells. The scheme was originally…
Optimal design of shell-graded-infill structures by a hybrid MMC-MMV approach
Chang Liu, Zongliang Du, Yichao Zhu +3
In the present work, a hybrid MMC-MMV approach is developed for designing additive manufacturing-oriented shell-graded-infill structures. The key idea is to describe the geometry o…
On speeding up an asymptotic-analysis-based homogenisation scheme for designing gradient porous structured materials using a zoning strategy
Dingchuan Xue, Yichao Zhu, Shaoshuai Li +3
Gradient porous structured materials possess significant potential of being applied in many engineering fields. To accelerate the design process of infill graded microstructures, a…
An efficient Moving Morphable Component (MMC)-based approach for multi-resolution topology optimization

In the present work, a highly efficient Moving Morphable Component (MMC) based approach for multi-resolution topology optimization is proposed. In this approach, high-resolution op…
A magnification-based multi-asperity (MBMA) model of rough contact where the Greenwood-Williamson and Persson theories meet
Xu Guo, Benben Ma, Yichao Zhu
Contact analysis without adhesion is still a challenging problem, mainly owing to the multiscale and self-fractal characteristics of rough surfaces. Up to now, theories for analyzi…
Self-supporting structure design in additive manufacturing through explicit topology optimization
Xu Guo, Jianhua Zhou, Weisheng Zhang +3
One of the challenging issues in additive manufacturing (AM) oriented topology optimization is how to design structures that are self-supportive in a manufacture process without in…
Explicit three dimensional topology optimization via Moving Morphable Void (MMV) approach
Weisheng Zhang, Jishun Chen, Xuefeng Zhu +4
Three dimensional (3D) topology optimization problems always involve huge numbers of Degrees of Freedom (DOFs) in finite element analysis (FEA) and design variables in numerical op…
Topology optimization based on moving deformable components: A new computational framework
Xu Guo, Weisheng Zhang, Wenliang Zhong
In the present work, a new computational framework for structural topology optimization based on the concept of moving deformable components is proposed. Compared with the traditio…
