Paper Abstract

KDP (Potassium Dihydrogen Phosphate) crystal is a kind of electro-optic nonlinear optical material. With increase of the growth size of KDP crystal, the crystal will crack during the growth process, which restricts the development of technology on large-size crystal growth. So as to discover the mechanical behavior of crack of KDP during the growth, the mechanical testing of KDP crystal was performed, its material property of transversely isotropic was verified, Poisson's ratio and other key mechanical parameters are got. It's the necessarily step for the further research of the crack mechanism of KDP crystal.
