A BENCHMARK STUDY ON CRUSHING AND CUTTING OF PLATED STRUCTURES

A benchmark study on several closed-form solutions for the mean crushi ng strength and the cutting resistance of plated structures during col lision or grounding is carried out by comparing theoretical solutions with experimental data. Based on expressions which have been derived f or unstiffened structures, an extension of the methods is proposed for longitudinally and/or transversely stiffened structures. Dynamic effe cts on the crushing and cutting response are discussed, and applicabil ity of the quasi-static formulations to analyze the crushing and cutti ng damage of the structure in the dynamic situations is investigated.
