Dynamical accelerated performance measure approach for efficient reliability-based design optimization with highly nonlinear probabilistic constraints

Behrooz Keshtegar, Souvik Chakraborty

Abstract: Highlights•A dynamical accelerated performance measure approach (PMA) is proposed to improve efficiency and robustness of RBDO.•A novel merit function is proposed to select the dynamical control factor in DCC.•Dynamical chaos control is accelerated between 2 and 0 to improve the convergence properties of FORM in PMA.•Proposed PMA –based DCC method provides efficient and robust results compared to existing RBDO-based PMA methods.
