Implementation of Ductile Damage Models to Determine Constraint Parameters for Ductile Materials: Phase 1 — Generic Constraint Conditions

J. Beswick, P. James, J. Sharples
Proc. ASME. PVP2020, Volume 6: Materials and Fabrication, V006T06A012, August 3, 2020
Paper No: PVP2020-21492
DOI: https://doi.org/10.1115/PVP2020-21492
...Abstract Abstract It has been observed that steels which are operating in the ductile regime demonstrate greater resistance to tearing under conditions of reduced crack-tip constraint. Constraint is influenced by both geometry and load conditions. For example, fracture toughness specimens...
