摘要:
对简单的板壳结构在爆炸载荷作用下的塑性响应特性进行了试验和数值仿真。运用Hyperworks和LS-DYNA程序,对基于两种不同钢材料模型建立的数值仿真模型进行计算,以试验结果为标准衡量不同材料模型在本试验条件下适用性,结果表明分段线性弹塑性模型适用于钢材料变形研究。得到不同空气域尺度对流固耦合数值仿真结果的影响,在保证计算精度并提高计算效率基础上,计算尺度应当为钢结构尺寸的3~5倍,计算尺度为钢结构尺寸3倍时,计算与测量结果偏差为2.5%;计算尺度为钢结构尺寸5倍时,计算结果几乎与试验值相当。
Abstract:
The elastoplastic response of shell structures under blasting was researched by experiment as well as numerical simulation. Based on the software of Hyperworks and LS-DYNA, numerical models on two different steel materials were set up and simulated. The applicability of different material under the experimental conditions was evaluated according to the experimental standard and the results indicate that piecewise linear elastic plastic model is applicable for the study of the deformation of steel material. The effect of different simulation scale on fluid solid coupling numerical simulation was clarified. To ensure the calculation accuracy and improve the calculation efficiency, the scale of numerical simulation should be about 35 times larger than the size of the steel structure. The calculation deviates 2.5% from the experiment result when the size is 3 times, while the calculation is similar to the test data when it is 5 times.
