Contemporary approaches to reducing weld induced residual stress
Residual strains around cold worked holes from statistical view
Cold working a hole decreases tendency of fatigue crack near the hole to initiate or growth. It is due to creation some compression tangential residual stresses around the hole. But there are many uncertainties which affect on residual strain and so...
Numerical investigation of the effects of constraint design on 5XXX Al Alloy GTA Welding
One of the most conventional approaches of quality control in metal weldments is the evaluation of
residual stresses and distortion. Constraining the structure during welding, is the significant key parameter for...
Impact of Residual Stress and Elastic Follow-up on Fracture
The presence of tensile residual stress in cracked structures combined with external loading can lead to circumstances where a structure may fail at a lower applied load than when residual stresses are not present. This is taken into consideration...
COMPARISON OF METHODS FOR PREDICTING THE INFLUENCE OF RESIDUAL STRESSES ON BRITTLE FRACTURE
This paper compares different methods for predicting the
influence of residual stresses on brittle fracture. Comparison is
made between fracture predictions of a local statistical
approach based on the Beremin type model...
Influence of Residual stress on the fracture behaviour of an Aluminium alloy
Influence of residual stresses on fracture response of an Aluminum alloy is investigated. Cylindrical flat ended
punching tools are employed to introduce residual stresses on 15mm thick C(T) specimens. The residual stress...
A numerical and experimental Investigation into the generation of Residual Stress in fracture specimens Using local compression
The influence of residual stresses on the fracture behaviour of materials is of fundamental importance for accurate and reliable structural integrity assessments of components and structures In this paper residual stress fields are introduced...
Measurement and Prediction of Residual Stress Generated by Local Compression
In order to assess the effect of a residual stress field on the fracture behaviour of materials, a well-defined residual stress field, with known characteristics, such as triaxiality, must be generated in a controllable and reproducible manner...
Combined Effect of Residual Stress and Loading History on Brittle Fracture
The aim of this paper is to examine the influence of residual stress (RS) and loading history on the subsequent
low-temperature cleavage fracture resistance of ferritic steel structures such as pressure vessels. Three...
