An artificial reef is normally composed of small concrete blocks stacked together. However, a structural analysis should be considered especially if the structure is not of single, large block construction, such as artificial reef blocks, which are stacked on each other. Namely, the safety reviews assume the stress and strain of a structure insignificant and focus only on the fluid analysis. Because of the complexity of fluid flow behavior, a coastal structure was assumed to be a rigid body for structural safety reviews. A design modification was suggested to prevent/minimize water ingression into the system which was further analyzed and proved to be efficient based on the FSI methodology.This study discusses a method for estimating the structural stability of a coastal concrete structure with an emphasis on sliding and overturning due to tidal current or waves. Water is made to impinge on the latch assembly and the/those water accumulated regions observed in the simulation were compared with the test results which are found to have good correlation. Since it can handle problems involving free surfaces, deformable boundaries, moving interfaces, extremely large deformation, and crack propagation, this was found to be an ideal technique for simulation. SPH is a mesh-free method used to simulate fluid flow and has found its application in many engineering problems & fluid structure interaction (FSI) models. Virtual validation becomes a viable option and with proper correlation work it helps to address these types of problems at low cost and in early stages of product development The latch is subjected to an impact by a jet of water, modelled using Smoothened Particle Hydrodynamics (SPH) technique. Stringent safety criteria have given rise to unconventional test methods that are time-consuming and hence necessitate virtual validation techniques.
Intrusion of water possible into the latch system can be disastrous depending on the climatic conditions. Hence, any exposure of electrical/electronic components to water make them susceptible to short circuits, corrosion etc., thereby may make it the functionality of systems and increasing the chances of failure in these devices. With the growing trend and advancements, automotive electronics is becoming more complex and prevalent. A wide range of factors like safety, ergonomics, and security influence the development of these latches to eliminate safety. It primarily aims to provide security of the occupants by securing the door system by ensuring timely locking and unlocking of the doors. An automotive door latch that functions manually or electronically is a vital component of a door closure system.
