Calculation method of bulkhead break size of ship with short blast warhead
Based on the energy conservation and momentum theorem,the plastic deformation deflection of the target plate is calculated,and the limit plastic strain is taken as the criterion,the calculation method of the fracture size in the cent-ral area of bulkhead structure under the blast wave load is established,and the short range air explosion model test is carried out.The experimental results show that the calculation method established in this paper has a certain accuracy.The relative error between the theoretical calculation results and the experimental results in this paper is 14.2％,and the error between the theoretical calculation results and the experimental results in references is 10.9％.It can be used to quickly estimate the frac-ture size of bulkhead structure under the action of explosion shock wave.
