摘要：

A new method for calculating the dynamic stress intensity factor of a pre-cracked bending specimen used in instrumented impact tests is proposed by making use of a line-spring model. The present method enables the one-dimensional analysis of a two-dimensional crack problem. It is applied to the dynamic stress intensity factor analysis of a pre-cracked three-point bending specimen and a pre-cracked four-point bending specimen. The results obtained from the present method are in reasonably good agreement with the two-dimensional finite element solutions or the experimental results.
