Structures that are subjected to compressive loads may experience not only local fractures but also buckling deformations due to instability. Furthermore, the performance of the structure can also be influenced by uncertain factors. This paper develops a surrogate model-based method for reliability-oriented buckling topology optimization under rand...
The material redistribution abilities of traditional deterministic topology optimization are effective in addressing stress‐related design issues in thermal elastic structures. However, uncertainties are inevitable in real‐world. The structural strength of a design, achieved through deterministic topology optimization, is highly susceptible to thes...
To achieve an ideal balance between cost and robustness, reliability and structural safety, this paper presents a unified robust reliability-based topology optimization (RRBTO) approach for continuum structures considering loading uncertainty for the first time. An optimization model of minimizing a linear combination of mean and standard deviation...
The objective of this work is to build a useful-response-surface-based reliability design approach for solving stress-constrained optimization problems taking into consideration load uncertainty. To this end, a reliability optimization problem of minimizing the volume fraction while satisfying a global probabilistic stress constraint is formulated,...
Currently, most works on synchronous optimization of composite topology and fiber orientation are all carried out under deterministic conditions, where the influence of uncertain factor on design optimization of fiber-reinforced composite structures is ignored. In this work, an effective probabilistic reliability-based topology optimization (RBTO)...
Currently, most of the piezoelectric structures are designed under deterministic conditions, where the influence of uncertain factors on the output motion accuracy is ignored. In this work, a probabilistic reliability-based topology optimization method for piezoelectric structure is proposed to deal with the working voltage uncertainty. A nested do...
