Recent research

Machine-specified Ground Structure Method

The topology of 2D truss structures can be self-generated using the graph embedding and the policy network. The self-generated topologies are further utilized to generate the machine-specified ground structure, which can be applied to solve topology optimization problems with singular optimal solutions. Click the figure to see the self-generation process of a truss based on a 6×3 node-set. Journal paper link

Form-finding of Aluminum Alloy Reticulated Structures

A quantitative index to evaluate the constructional convenience of free-form aluminum alloy reticulated shells is proposed considering the details of the aluminum alloy gusset joint. A form-finding method of the free-form shells is proposed based on the index mentioned above. Journal paper link

Prediction of Buckling Load of Imperfect Reticulated Shell using Machine Learning

The consistent imperfection method is modified according to the specification on the constructional errors. Based on the modified consistent imperfection method and supervised machine learning, a prediction method of the non-linear buckling load of imperfect spatial structures with low calculation cost is proposed.

Shape Optimization for Aluminum Alloy Reticulated Shells

A shape optimization method of aluminum alloy shells considering joint rigidity is proposed by means of the genetic algorithm. The method can improve the non-linear buckling load of a spherical shell without significantly change its geometric appearance. Journal paper link
