Abstract

Vehicles face significant risks of structural damage and instability during water entry, emphasizing the need for effective load reduction to ensure success. Existing rigid devices have limitations in load capacity and stability. This paper proposes using a hyperelastic material with excellent impact resistance and resilience. Upon free surface impact, hyperelastic bodies deform, storing impact energy as strain energy to reduce load. Once in the water, they recover shape, converting strain energy to kinetic energy, aiding media transition. However, significant deformation and recovery lead to complex multiphase flows and structural responses, posing challenges in fully understanding the load reduction mechanisms. During impact load reduction, the energy conversion mechanisms based on deformation behavior are elucidated. In water, the fluid-structure coupling characteristics, including cavity flows, energy recovery, and elastic wave propagation resulting from the deformation of the cylinder, are investigated. Furthermore, a range of hyperelastic materials with enhanced energy conversion efficiency and unloading performance are identified.

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.
