Theoretical Solution of Square Shell Under Internal Pressure
(The American Society of Mechanical Engineers (ASME), 2025)Pressurized enclosures with square cross sections are common components in the petrochemical industries. Since no theoretical solutions are available, analysis and design of such components mainly rely on empirical or ... -
On the Use of a Stress-Independent Threshold Stress Term in Creep Life Models
(The American Society of Mechanical Engineers (ASME), 2025)The concept of effective stress, where the applied stress is reduced by a resisting or threshold stress, is often used in fatigue and creep strain rate models, but seldom in single-line equation creep life models. Recently, ... -
Tensile Strain Capacity of an X70 Pipe With Internal and External Semi-Elliptical Crack Under Bending and Tension
(The American Society of Mechanical Engineers (ASME), 2025)This paper studies an in-depth examination of the tensile strain capacity (TSC) of an X70 pipeline containing an internal or external semi-elliptical crack when exposed to bending or tension. Comprehensive TSC evaluations ... -
Lateral and Transverse Stiffness Requirements for Supports of Pipeline Systems Conveying Fluids
