Abstract

Abstract

The transient is opachic and isochromtic tringe patterns are acquired at a blast loading.Two kinds of ways are used to study transient stress field in infinite plate subjected to concentrated blasting load,the different calculation results are contrasted.A new verifying method for judging the orders of two kinds of fringes is devised if stress wave is reflected at the free boundary.
