弹性压缩波在一维接触非线性介质中的传播
Propagation of compressional elastic waves through a 1-D medium with contact nonlinearities
摘要：
从理论和数值两方面研究了一维单色弹性波在裂纹中的传播。裂纹由非线性跳跃条件模拟。通过摄动分析估计了单个裂纹的平均扩张和谐波的产生，并通过谐波平衡法计算。与周期性和有限网络的裂纹，直接数值模拟进行比较，与布洛赫-Floquet的分析。
英文摘要：
Propagation of monochromatic elastic waves across cracks is investigated in 1D, both theoretically and numerically. Cracks are modeled by nonlinear jump conditions. The mean dilatation of a single crack and the generation of harmonics are estimated by a perturbation analysis, and computed by the harmonic balance method. With a periodic and finite network of cracks, direct numerical simulations are performed and compared with Bloch-Floquet's analysis.
