I have posted a report that updates our work on fracture of notched rods in torsion. This paper describes additional experiments and computational simulations of the problem. The paper is given as a hyperlinked PDF with links to animations, images and data to allow further exploration of the results. Link to paper: Mode III Fracture in Rods Under Torsion: Experiments and Simulations
Fracture surface reconstructed from segmentation of micro-CT scan of notched PMMA rod fracture in pure torsion loading. Rod diameter is 19 mm.
