Treatment of the subject of tearing instability. Final report

Abstract

This report presents an analysis of the subject of tearing instability of low strength steels in two parts: The first part is an intensive theoretical treatment of the subject, and the second part is an initial experimental exploration and verification of the theory. The analysis shows that tearing instability, or abrupt cracking above the materials transition temperature, is controlled by a newly defined material property, T, the tearing modulus (non-dimensional). The 3-point bending tests discussed demonstrate that T is the controlling parameter for instability under fully plastic plane strain conditions. The report in total broadly addresses the application of the theory for both analysis and testing purposes.
