Many obstacles such as minefields, barbwire entanglements, tank ditches and other fortifications are used to paralyze the forward momentum of mechanized armed forces. To combat this the Grizzly tracked vehicle was developed for the United States Army. Due to the Grizzlygass mission various sensors, laser systems, hydraulic lines, wires and cameras are mounted on the armor hull, which are exposed to various types of landmine detonation and fragmentation. This thesis studies the effects of shock waves and fragmentation on the survivability of the equipment mounted on the Grizzlygass armored hull. Models of an OZM-72 antipersonnel mine are developed and used to simulate the detonation and fragmentation phenomena. The analysis results obtained from the models provide a basis from which design guidance can be formulated for protecting equipment or personnel from this threat.
