Appendix T in NH [7] provides three expressions for determining strain range [8] using elastic analysis and, if these rules cannot be satisfied, additional rules are provided,presumably less conservative, based on the results of inelastic analyses which require detailed constitutive models of material behavior under time varying loading conditions.For the CRBR, these behavioral models were […]

Section 17.4.4.3.9.3, Consideration for Elastic Follow-up, provides a fairly extensive discussion of what constitutes elastic follow-up, where it is considered in the current rules, and guidance on how to implement that consideration. Also addressed is the background for the provisions for pressure-induced discontinuity stresses in the HBB-T-1330 rules for strain limits and the HBB-T-1430 rules

Movement of loads covered by this Standard shall be in accordance with the Standard’s requirements but not necessarily with its recommendations. The word “shall” is used to denote a requirement, the word “should” is used to denote a recommendation, and the word “may” is used to denote permission, which is neither a requirement nor a

This Standard establishes common terminology and provides guidelines for the quality. description, princ-ple of operation, selection, operation, installation, and flow calibration of capillary tube thermal mass flow-meters and mass flow controllers for the measurement and control of the mass flow rate of gases. The content of this Standard applies to single-phase flows of pure gases

This Standard describes the common variable area flowmeter. This Standard does not attempt to standardize dimensions because the commercial products differ too widely. The variable area meter is manufactured in a variety of designs. This Standard addresses only those meters based on a vertical tapered tube of round or a modified round cross section. Specifically

This Standard, ASME MFC-11M, gives guidelines for the selection, installation, calibration, and operation of Coriolis meters for the determination of mass flow, den-sity, volume flow, and other related parameters of flow-ing fluids. It also gives appropriate considerations re-garding the fluids to be measured. The content of this Standard is primarily applied to the metering of

This Standardestablishesmethods for determining the influence of in stallationconditions or flow patterns on the performance of flow metersin closed conduits (i.e., pipe, ducts, etc.). This Standardalso addresses (a) meansand terminology for defininga reference condition for flow calibration of a particular flow‑meter; and (b) guidelines for extrapolation and interpolation of installationeffects to unteste dpiping conditions.This Standard
