| 摘 要： | 利用超声方法测量核电主螺栓的应力，需要精确地测定螺栓材料的三阶弹性常数。本文从非线性弹性理论出发，求解应变量方程，导出了各向同性材料中三阶弹性常数的超声测量公式。

| Abstract: | It is needed to measure the third - order - elasticity of the bolt material precisely when we measure the stresses of main bolts in the nuclear power station by using ultrasonic method. In this paper, we, on the basis of the theory of non-linear elastic wave, solve the equation of strain energy. We also give the ultrasonic measurement formula of the third-order-elasticity in isotropic material. |
