Linwei graduated from Shanghai Jiao Tong University in 2011 and started his PhD in Sheffield researching rationalization techniques for trusses and yield-line patterns generated via layout optimization. After completing his PhD, he joined LimitState Ltd to develop engineering software tools. In July 2016 he rejoined the Computational Mechanics and Design Group as a Post-Doctoral Research Associate. His work now focuses on computational design optimization of building structures.

Yield-line analysis of slabs using discontinuity layout optimization

Yield-line pattern
One of the oldest and most fundamental problems in the field of engineering mechanics involves calculation of the amount of load that can be carried by a structure, and in identifying the associated failure mechanism (layout of failure planes, or ‘discontinuities’). Discontinuity layout optimization (DLO) is an engineering analysis procedure...

Mathematical, Physical and Engineering Sciences, 470 (2168), (Full Text)., Abstract: The yield-line method of analysis is a long established and extremely effective means of estimating the maximum load sustainable by a slab or plate. However, although numerous attempts to automate the process of directly identifying the critical pattern of yield-lines have been made over the past...
