Abstract

Closed-form expressions are derived for linear elastic axial displacement and bending deflection of circumferentially cracked pipe under combined tension and bending. Formulas are then presented for the applied tearing modulus for: 1) load control and 2) displacement-controlled loading. These formulas are very useful for predicting crack initiation and instability under small-scale yielding conditions.
