摘要(Abstract)：
通过工程试验研究,观测并计算了水下爆炸引起的舰船模型应力应变现象。根据舰船材料强度理论、分析试验结果,总结了舰船模型应力应变受水下爆炸冲击的变化规律,指出舰船模型底板的应力应变与舰船底板的结构尺寸有关。试验给出了水下爆炸时舰船模型的应变数值和应力计算结果,以及舰船模型底板沿短边方向产生最大的应力与应变。
The stress and strain changes of warship model induced by underwater explosion were observed and calculated in the experiments.According to the existence theories on strength character of warship material and based on the analysis of experiment results,the stress and strain change laws of warship model induced by underwater explosion were summarized.It was indicated that the stress and strain changes of the motherboard of warship model were related to its structure and size.Strain values of warship model induced underwater explosion were monitored in the experiments and its corresponding stress values were calculated according to formulas.The maximum stress and strain came into being along short border of the motherboard of warship model.
