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

  • Charles Hall
Part of the NATO Advanced Study Institutes Series book series (ASIC, volume 49)

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.
