چکیده مقاله
Underwater explosion is one of the main threats to offshore installations Prediction of damages to such structures as Jacket Template J T Platform is one of the priorities in today’s research on offshore structures In the present study, underwater explosion is simulated using Finite Element FE code and its effect on J T Platform is investigated To verify the correctness of modeling underwater explosion in the FE code, a thin rectangular plate, subjected to a shock wave was modeled and the result of analysis of this model was compared to those cited in the literature and excellent correlation was observed After successful model validation, a 79 85m high J T Platform, comprising of 258 pipe members, was modeled The pipe's material was assumed to be elasto plastic following Johnson Cook strain rate hardening rule Different amounts of charge mass were placed at different distances from the offshore platform and their effect on the structure, were investigated
