摘要: An apparatus for monitoring the growth of surface cracks in materials includes a servo-hydraulic test machine which applies load to specimen according predetermined loading regime designed induce crack specimen, UV laser illuminating with light having frequency greater than incandescent light, video camera and two dimensional imaging computer. Optionally, computer can be used control machine.
