摘要
采用应力波无损检测方法测试了结构集成材的动态弹性模量,并分析了动态弹性模量与抗弯强度之间的关系。结果表明,动态弹性模量与静态弹性模量和抗弯强度之间存在线性关系。
The dynamic elastic modulus of structural glued laminated timber is tested using a stress wave nondestructive testing method, and the correlation between the dynamic modulus of elasticity and the bending strength is analyzed. The results show that there is a linear correlation between dynamic elastic modulus, static modulus of elasticity and bending strength.
