Abstract

Simulating the random response of structures is a practical matter that is crucial for design, as the majority of masses operate on them according to random principles. This is the first publication to examine the random vibrations of a two-curvature shell that is supported by a viscoelastic foundation. The core layer is composed of numerous small layers that are arranged in accordance with biomimetic principles, while the two surface layers are composed of piezoelectric materials. This work has established the equilibrium equation system of the shell by integrating classical shell theory with nonlocal theory. The proposed problem has been resolved through the application of analytical solutions. The research problem has been rendered more comprehensible as a result of the experience obtained in analytical form, which is also the most intriguing aspect of this study. Furthermore, this investigation considers the impact of the flexoelectric effect on piezoelectric layers, with a particular emphasis on the viscous resistance parameter of the viscoelastic substrate. Despite the fact that this complicates the calculation expressions, it adds to the intriguing scientific significance of this research in relation to the oscillation of a two-curvature shell. The two-curvature shell is subjected to a stationary random load, and the response spectrum (displacement) is closely correlated with the input spectrum (excitation force) through the function transmission, which accurately represents the shell's response. This investigation has numerous valuable scientific implications, as the results are closely resembling reality.

期刊介绍： Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering. The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
