A New Constitutive Model in the Theory of Plasticity—Part II: Examples
(The American Society of Mechanical Engineers (ASME), 1995)This part of the paper presents several examples to further demonstrate the hardening model proposed in the first part of the paper. Closed-form solutions are achieved for a thin-walled tube ... -
Preliminary Design of Tubular Composite Structures Using Netting Theory and Composite Degradation Factors
(The American Society of Mechanical Engineers (ASME), 1995)Tubular products and process vessels built using fiber-reinforced composite materials provide significant advantages in applications that require corrosion resistance, high strength, and light weight. ... -
Cumulative Detection Probability as a Basis for Pressure Vessel Inspection Intervals
(The American Society of Mechanical Engineers (ASME), 1995)This work discusses use of the cumulative flaw detection probability as the basis for establishing pressure vessel inspection intervals. The method is based on the accumulated probability of ... -
Vibration of a Tube Bundle in Two-Phase Freon Cross-Flow
(The American Society of Mechanical Engineers (ASME), 1995)Two-phase cross-flow exists in many shell-and-tube heat exchangers. The U-bend region of nuclear steam generators is a prime example. Testing in two-phase flow simulated by air-water provides ... -
Peak Stress and Fatigue Assessment at the Saddle Support of a Cylindrical Vessel
(The American Society of Mechanical Engineers (ASME), 1995)The maximum stress in a saddle-supported cylindrical storage vessel is often the circumferential stress developed at the tips (or horns) of the saddle support. Although the peak stress at the ... -
