ABSTRACT
This chapter examines the properties of strain and strain-rate hardening of the material. It explores the shear fracture criterion was adopted to monitor the occurrence of the fracture. Selection of the fracture criterion and the determination of the related critical value are the most important tasks for the fracture analysis of the impacted structures. To predict the fracture of laterally impacted double hull side structures with acceptable accuracy, more experimental investigations are necessary using which reliable fracture criteria can be developed. The chapter explores three new lateral collision tests were conducted on models that were approximately one-seventh the scale of a double hull side structure. These are DH-5, DH-6 and DH-7. To improve the present harmonized common structural rules regarding the structural design against the effects of collision, it is necessary to provide the design collision scenario and perform the collision analysis using the scenario to obtain the extent of damage.
