Research output: Contribution to journal › Journal article › Research › peer-review

Abstract

A short review of experimental methods currently used in evaluating the velocity of fast crack extension is given. The technique of applying a surface deposited grid gauge has been innovated. This new technique involves a grid produced by a photo-chemical method and an electronic registration circuit based on integrated transistor-transistor logic. This new method has been applied to experimental studies of brittle crack extension in steel at temperatures between −115 and +22°C.
