【摘要】 本文通过理论推导，给出用一个三点弯曲实验就可以同时测定复合材料峰窝夹层板弯曲刚度和剪切刚度这两个重要弹性常数的原理。根据这一原理，得到一个简便、省时、易统计数据而且精度较高的复合材料蜂窝夹层板测试的刚度分离实验方法．更多还原

【Abstract】 In this paper,the test theorem that can simultaneously determine twoimportant parameters,bending and shearing stiffness. of honeycomb sandwich panel ofcomposites only using a Three-point Bending Test has been proposed based ontheoretical deduction. According to this theorem a new test scheme,namely“The TestMethod of Stiffness Dissociation of Honeycomb Sandwich Panel of Composites”withmany advantages,such as simple test operation,saving time and testing materials inexperiment and precise results, has been established.更多还原
