摘要
通过弯曲振动试验、纵波传播试验及纵波共振试验对胶合板的抗弯弹性模量进行无损检测 ,并分析了三种试验方法测定结果之间的关系。结果表明 :虽然不同方法测得的胶合板弹性模量值不同 ,但其间存在一定的内在联系。
The dynamic modulus of elasticity ( MOE ) in bending of plywood was measured by tests of flexural vibration, longitudinal transmission and longitudinal resonant vibration. The results indicated that the MOE of plywood by different nondestructive tests were different, but there was a correlation between them.
