“…The problem of a plate with a circular central hole subjected to surface tractions perpendicular to the edges of the plate is a classical example for shakedown analysis. Our previous research [26,27] confirmed the plastic limit and shakedown results of this example are in high agreement with the literatures, which further demonstrates our technique for shakedown analysis to be a viable and suitable numerical approach. Therefore, this benchmark problem is also employed in this section to illustrate the accuracy, reliability and efficiency of the proposed work flow in optimal designing structure in terms of shakedown load domain.…”

“…Abdalla and Megahed (2018) used the nonlinear superposition method to calculate the elastic shakedown limit loads of spherical vessels with radial and oblique nozzles based on Melan's lower bound shakedown theorem and then compared with the experimental test results. Huang et al (2019) developed a numerical method for extended shakedown analysis based on a two surface plasticity model of kinematic hardening. Zhuang et al (2019) developed a 3D analytical shakedown solution in railway structure under multiple Hertz loads.…”

“…Composites of multiple phases were studied by homogenization theory [22,23], and non-periodic random composites, auto modeling techniques, and statistical measures [24][25][26] were involved. Different hardening models of material were analyzed [25][26][27][28][29][30][31][32], as were temperature loads [28,29] and multidimensional load domains [6,30]. In the macro scale, besides pressure vessels and piping, components of high-speed train were also studied [31,32].…”
