Unlisted components can have pressure ratings but the owner and/or the designer has the responsibility to verify that the design, materials, fabrication, examination, and testing of the component meet the requirements of ASME B31.3.

ASME HPHT Standards

Both yield and tensile strength, as well as the stress-strain curve, are considered in the FEA. Charpy V -notch impact tests (toughness tests) are required in essentially all cases. For high pressure vessels, the failure mode of ductile burst is rarely encountered. It is more important to ensure that fast fracture does not occur, so the emphasis in ASME code ductile failure criteria for impulsively loaded Ductile Failure Limit State Design of High Strength ASMEAbstract. Ductile failure criteria suitable for application to impulsively loaded high pressure vessels that are designed to the rules of the ASME Code Section VI11 Division 3 are described and justified. The criteria are based upon prevention of load instability and the associated global failure mechanisms, and on protection against Ductile Failure Limit State Design of High Strength ASME

Design by analysis of ductile failure and buckling in Ductile Failure Limit State Design of High Strength ASMEThe ASME Code provides procedures for design based on limit analysis and on plastic analysis, which may include strain hardening and/or large deformation effects.In plastic analysis, the GPD load is defined by applying a criterion of plastic collapse to a characteristic loaddeformation curve calculated for the vessel. The ASME twice elastic slope (TES), criterion is based on an empirical Ductile Failure Limit State Design of High Strength ASME

Ductile Failure - an overview ScienceDirect Topics

Ductile failure is also known as plastic collapse, general yielding or ductile overload, and is the failure mode that occurs when a material is simply loaded to beyond its ultimate tensile strength (see Chapter 4). Purely ductile failures tend to be rare in service, as the first principle of structural design is to ensure that a component does Ductile Failure Limit State Design of High Strength ASME Efficient, scale-bridging simulation of ductile failure in Ductile Failure Limit State Design of High Strength ASMEThe relevant limit state for static design is ductile failure or plastic collapse. The current safety factors for the design stress were defined based on experience and empirical data of low strength steels. A systematic investigation of the failure properties of high strength components is missing.

state on ductile fracture. McClintock and Rice and Trace}' have shown that void growth associated with ductile failure depends strongly on stress state. Tensile test specimens of notched cylindrical geometry provide an attractive means of introducing triaxial tension and of On the influence of state of stress on ductile failure Ductile Failure Limit State Design of High Strength ASMEResidual stress present in coupons used for fracture testing will influence the experimental determination of fracture toughness. Triaxial residual stress (e.g., due to welding) can alter both the driving force for fracture and the crack-tip constraint at a specified load, so that the apparent toughness of a coupon depends on the residual stress present.

The rea for this design philosophy is to have lower limits for types of stresses that are more likely to lead to abrupt or catastrophic failure. A similar design philosophy should be implemented for inelastic analysis and strain-based acceptance criteria.

Strain-Based Design of Pipelines

Strain-Based Design This is a design method that places a limit on the strains at the design condition rather than the stresses. Load Control Load control describes a situation where the combination of load and displacement is controlled by the load variable, where a change in shape will not change the load. The Short Shank RedemptionFurthermore, connections are often designed so that the controlling limit state is not the bolt shear capacity, but rather some other, more ductile limit state. Often, the bearing strength or block shear strength of the connected material controls the design of the connection, particularly when thinner plies are joined, which fortunately is Ductile Failure Limit State Design of High Strength ASME

Recent work has shown that ductile failure highly depends on the stress state characterized by both T and the Lode parameter L, which is related to the third deviatoric stress invariant.

A micromechanics-based ductile fracture initiation theory is developed and applied for high-throughput assessment of ductile failure in plane stress. A key concept is that of inhomogeneous yielding such that microscopic failure occurs in bands with the driving force being a combination of band-resolved normal and shear tractions.
