... Abstract This paper proposes a new analytical derivation to incorporate bending and torsion into collapse calculation, further pushing the already existing approach of combined loading equivalent grade proposed in API TR 5C3 (2019) Clause 8.4.6 Eq.

... cycles with stress amplitude below the rated yield strength showed substantial growth of plastic strain in only a few cycles. Combined-load tests on small-scale tubular P110 specimens loaded with axial force and internal pressure cycles also demonstrated pronounced near-yield load effects. We discuss...

... Abstract Triaxial evaluation of loads is used extensively for casing and tubing string design and analysis. The paper presents a method of determining the triaxially based collapse strength of casing and tubing subjected to simultaneous axial and internal pressure loads. The triaxially based...

... Abstract API rotary-shouldered drill stem connections have a seal surface that is required to carry internal pressure. We assume that this seal will hold the pressure from routine drilling operations, but drill stem tests, stuck pipe, or other special situations can apply much higher...

As the core permeability decreases, the time required for the core internal pressure to approach the external pressure increases, requiring longer equilibration times...
