摘要:
A heuristic model is presented which quantifies the effect of a compressive residual stress of the dispersion on a Rayleigh wave propagating over a cracked surface. The model shows that a residual stress acting on the outermost part of a surface, and extending for about 20% of the crack depth within the sample, reduces the dispersion of the Rayleigh wave by about 70%.
