Moire interferometry for dynamic fracture study
DOI:10.1016/S0143-8166(02)00092-1.png)
摘要
En 中文
A procedure of fabricating zero-thickness grating, an optical setup and a recording system for dynamic moire interferometry and a data reduction procedure via nonlinear regression analysis are described. The utility of these procedures are demonstrated by determining the dynamic fracture parameters associated with a rapidly propagating crack in thin 7075-T6 aluminum fracture specimen.
