BSI WEE/37 (Acceptance levels for flaws in welds) panel 11 (Strain Based Analysis) is preparing an additional Annex for BS 7910:2013 to extend the fracture assessment capability of the standard to nominal strains that are beyond the material yield strain. Transforming Stress Limited are members of WEE/37 panel 11.
Transforming Stress Limited staff developed the stress analysis guidelines (Annex C) of BS 7608:2014 ('Guide to fatigue design and assessment of steel products'). Our staff wrote Annex C before joining Transforming Stress Limited.
ISO/TC 44/WG 5
Transforming Stress Limited staff sat on an ISO working group ('Welding Simulation') and co-authored ISO/TS 18166:2016 ('Numerical welding simulation -- Execution and documentation'). Our staff co-authored ISO/TS 18166:2016 before joining Transforming Stress Limited.
The V Factor
Primary and secondary stresses are differentiated in assessments of component integrity. It is especially important to correctly determine the relative contributions of these two stress types when making assessment of flaw tolerance in welded joints. Transforming Stress Limited staff proposed the V factor for this purpose. V was an adaption of existing methods, and it now used in the following codes and standards.
