Abstract

The paper describes an experiment which performs in-situ loading of a small compact tension
specimen in a scanning electron microscope. Images are collected throughout a number of successive loadincg
cycles. These are then analysed using digital image correlation (DIC) in order to produce crack flank
displacements as a function of load. This data is then compared with a simple elastic approach, and it is concluded
that elastic-plastic analysis is required in order to accurately capture the displacements close to the crack tip. A
simple approach due to Pommier and Hamam is therefore employed. This gives a better representation of the
data, but predicts a variation of crack tip displacement, ?, which is difficult to explain from a physical perspective.
The need for a more sophisticated analysis of the data is therefore highlighted.
