摘要:
根据Gibson理论模型确定出泡沫铝的力学参数，设计出不同密度组合的5种数值计算模型，利用非线性动力学程序LS-DYNA研究了爆炸载荷作用下，应力波在泡沫铝夹层三明治板中的传播规律。对其缓冲吸能、衰减应力波特性进行对比分析。研究结果表明：由Gibson理论模型确定出的泡沫铝力学参数，在Crushable_Foam本构模型中能够较好地反映应力波在不同介质界面间的反射与透射情况，与弹性波理论吻合度较高。在总体密度相同的情况下，H-M-S梯度结构对爆炸冲击波具有更好的缓冲效果。其对应力波的持续削弱能力和爆炸冲击能量的持续吸收能力都要强于其他结构。
Abstract:
Mechanical parameters of aluminum foam, deduced according to Gibson theoretical model, were selected for five different density combinations in the design of numerical modeling. Propagation rules of stress wave in aluminum foam sandwiched plates were studied using nonlinear dynamics software LS-DYNA. The energy adsorption and properties of stress wave attenuation were analyzed. The results show that the mechanical parameters of aluminum foam deduced by Gibson theoretical model could well represent the reflection and transmission of stress wave in the interface between different medium in Crushable_Foam constitutive model. And the result is coincident with elastic wave theory. In the case of equal overall density, the H-M-S gradient structure have better buffer effect under blast wave, and its sustainable capacities to weaken the stress wave and absorb explosive impact energy are better than the other structures.
