Direct plastic structural design by chance constrained programming (2018)
Ngoc Trinh Tran ; Hermann G. Matthies ; Georgios Eleftherios Stavroulakis ; Manfred Staat
We propose a stochastic programming method to analyse limit and shakedown of structures under random strength with lognormal distribution. In this investigation a dual chance constrained programming algorithm is developed to calculate simultaneously both the upper and lower bounds of the plastic collapse limit or the shakedown limit. The edge-based smoothed finite element method (ES-FEM) using three-node linear triangular elements is used.
