用共振法、衰减法和声速法测定了五种木材试样的动态弹性模量和内耗,并分别与常规方法测得的静曲模量相比较,明确了各种方法之间是等价的。对推广这些方法于木材力学的研究有一定意义。
The dynamic modulus of elasticity and internal friction of five kinds of wood samples were measured by resonance method, attenuation method and acoustic velocity method. Compared with the static modulus measured by the conventional method, it is clear that the methods are equivalent . The promotion of these methods in wood mechanics research has some significance.
