Experimental determination of high-acceleration shock characteristics of industrial marine fenders / David N. V., Adelin Khairina M. S. and Vipin Gopan

Engineering systems are often subject to complex loading mechanisms including accelerated mechanical shock during transportation, handling, and operations. Shock can be understood as a drastic, irregular change in acceleration experienced by an object due to impact at a very short period. This paper...
