A Model For Fully Formed Shear Bands

reportActive / Technical Report | Accession Number: ADA254713 | Open PDF

Abstract:

An asymptotic analysis of the morphology of a fully formed shear band is given for a simple flow law in a perfectly plastic material. Scaling laws are given for the maximum strain rate and the width of the band.
