采用解析和数值方法研究了由金属泡沫芯和金属纤维层合板组成的夹持方形夹层板(SSP)的低速大质量冲击。基于修正刚塑性材料近似(RPMA),对方形FML夹芯板低速碰撞(LVI)进行了计算。进行了数值模拟,并与分析结果进行了比较。详细讨论了材料参数和冲击位置对动态性能的影响。本文的工作为方形FML夹层板的低速碰撞预测提供了一种简便有效的分析方法。
The low-velocity impact via a heavy mass on clamped square sandwich plates (SSP) composed of metal foam core and fibre-metal laminate (FML) face-sheets is studied by analytical and numerical methods. Low-velocity impact (LVI) is formulated on square FML sandwich plates based on modified rigid-plastic material approximation (RPMA). Numerical simulations are conducted, and then compared with analytical results reasonably. Influences of the material parameters and impact location on the dynamic behaviors are discussed in detail. This work provides an efficient and simply analytical method to predict low-velocity impact for square FML sandwich plates.
