# The Construction of a Macro Element for use in Three Dimensional Fracture Mechanics

Chapter

## Abstract

The stiffness derivative technique is used to compute stress intensity factors. The crack region is modelled by means of a macro element which contains, a priori, a high density of nodes in the vicinity of the crack front and is compatible with standard 20 node elements that it abutts.
