Last week I admitted Mr. M in the predawn hours of an evolving M.I. I had forgotten his name.

Through sleep-deprived eyes and the apparition of a pachyderm poised on my patient’s chest, I saw clearly what the years had hidden. Thankfully, there was business to conduct, orde...

Nondestructive evaluation of the prevailing compressive residual stress in the shallow subsurface layer of surface-treated metals is greatly complicated by the accompanying surface roughness and cold work. A high-precision laser-ultrasonic technique has been developed to study the feasibility of SAW dispersion spectroscopy for residual stress assessment on surface-treated metals in a wide frequ...
