Introduction

The package provides information needed to set up and present a short practical demonstration in a lecture.  This LDP (Lecture Demonstration Package) is centred on crack propagation in inflated balloons. It would be suitable for a first year undergraduate course covering the basics of fracture.

After covering this lecture you should know:

  • Stress Fields in Internally Pressurised Cylinders
  • Griffith Treatment of the Energetics of Crack Propagation

It would be useful to look at the TLP on Brittle Fracture before you start.
