Effect of optical penetration on laser generatedthermoelastic ultrasound in solids
《Chinese Journal of Acoustics》1995年第4期289-299,共11页FANG Qiping BAI Yuhai and C. F. Ying(Institute of Acoustics, Academia Sinica. Beijing 100080) 
The effect of optical penetration on laser thermoelastically-generated ultrasound in non-metallic solids is studied theoretically on the basis of the thermoelastie equations. In one-dimensional model, on the assumptio...

New thermoelastic technique for detection of residual stress distribution in solids
《Chinese Journal of Acoustics》1995年第2期97-106,共10页QIAN Menglu(Institute of Acoustics. Tongji University, Shanghai 200092) 
Bascd on the non- linear thermoclastic theory, the temperature field and displacement field in a prestressed sample are obtaincd when a one-dimensional heat disturbance is applied to it. By using piezoelectric equatio...

Thermoelastic equivalent circuit for laser ultrasound
《Chinese Journal of Acoustics》1995年第1期66-72,共7页LI Zhichun (Institute of Acoustics, Tongji University, Shanghai 200092) 
On the basis of thermoelastic theory, a thermoelastic equivalent circuit model for laser-generated ultrasound has been proposed. With this model, laser-heated region is des cribed as a three-port electrical circuit wh...
