Non-linear transient dynamic response of rectangular plates under shock loading

Experimental and numerical investigations were carried out on clamped recta ngular plates subjected to underwater explosion loading. Experiments were c onducted on rectangular plates of size 0.55 x 0.45 x 0.004 m using a box mo del set-up under air-backed conditions in a water tank detonating small cha rge weights of PEK-I explosive. Corresponding plastic deformation of the pl ates were measured for different charge weights and stand off distances. Nu merical analysis was carried out using the MARC finite element code for var ious test conditions and the results are compared with experimental results .
