试件在激光与材料非熔凝作用下动态变形过程实时测量的结果表明 :薄板在激光照射下所引起最终变形的方向取决于材料的性质 ,可能是朝向激光束或背向激光束。研究结果进一步完善了薄板激光弯曲的变形机理 ,并为研究薄板激光弯曲过程奠定了基础。

Experimental results show that final deformation direction of the specimen depends on the composition peculiarity of material, away from the laser beam or towards the laser beam through measuring the dynamic micro-deformation of the specimen under the condition of non-melting by the means of laser beam reflex amplifier system. The conclusion perfects the mechanism of laser bending and lays a foundation of research on the process of laser bending further.
