中文摘要:
      在静应力产生的位移是有限位移,波产生的位移是无限小位移的假设前提下,用非线性声弹性理论,导出了正交静应力作用下的各向同性超弹性体的等效弹性常数,进而探讨了正交静应力与Lamb波波速的关系,得出了一些有实用价值的结论.可为Lamb波的应力测量提供理论基础。
英文摘要:
      On the assumption that the particle displacement caused by static stresses is finite displacement and the particle displacement caused by wave transmission is infinitesimal displacement, the theory of the nonlinear acoustoelasticity has been used to calculate the equivalent second order elastic constants of the plate with orthogonal static stresses acting on.The relationship between Lamb wave velocity and static stresses in metal plate is discussed.The result is valuable both in theoretical study and practical application, and can be the basis of stress measurement with Lamb wave.
