摘要
本文讨论了应用共振法测定复合材料试件弹性常数的基本原理和实验方法．文中考虑了剪切变形和转动惯量的影响．对现有的计算弹性常数的公顷式作了改进．提出了一个新计算公式测试结果的精度也得到大大提高。和轴向拉伸实验结果作了比较．结果是满意的。
The basic principle and experimental method are discussed to determine the elastic constants of composite material specimen.The effect of shear deformation and rotary inertia are considered in the paper.The existing formula for calculating the elastic contants is improved and an new calculation formula is preented. The precision of the test results is increased greatly ,and in comparison with the exeperiment of axial tension,the satisfied results are satisfied.
