Abstract

Abstract

An experimental system of blast model of three-dimension dynamic astigmatic photo-elasticity is established by using the ruby pulse laser apparatus. By detonated the column and trip-shaped charge at one side, two sidesor or in the mid-point, four dynamic stress fringe patterns of the same section at four different second are got, then the dynamic stress field of three kind of blast model is constrasted and analyzed. Finally the corresponding conclusions of blast effect are got.
- column and striped charge,
- dynamic photo-elasticity,
- blast,
- stress field,
- the point of detonated
