Abstract
The perovskite solar cell (PSC) emerges as one of the most burgeoning photovoltaic contenders, igniting tremendous research passion within academia and industry. This study addresses the critical yet challenging issue of nonlinear dynamic buckling and reliability analysis for the PSC with agglomerated carbon nanotube reinforced composite (CNTRC) stiffeners under triaxial impacts, simultaneously tackling high-dimensional uncertainties and various categorical factors for the first time. A deep virtual modelling technique, namely Tree-structured Parzen Estimator enhanced Gated Additive Tree Ensemble (TPE-GATE), is newly developed to depict the sophisticated relationship among high-dimensional and heterogenous categorical inputs, and the focused composite nonlinear failure response and reliability accurately and efficiently, circumventing extensive triaxial simulations across vast combinatorial spaces. Statistical information and risk probabilities regarding buckling behaviour are effectively furnished with the deep virtual model, which is essential for safety assessments and serviceability limit state design of the stiffened PSC. In numerical experiments, the superiority of TPE-GATE over popular meta-models is quantitatively demonstrated. Furthermore, parametric studies examining various critical factors influencing deterministic and stochastic failure responses are efficiently conducted using TPE-GATE. Ultimately, unique findings will facilitate informed decision-making and preventive strategies to enhance impact-carrying capacity, reliability-based safety design, and robust optimization of advanced solar composites.
期刊介绍:
The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials.
The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
