    Asme 9 and AWS D1.1: Mixed group welding & equivalent grouping

    Hi Kiwi, Thanks for the feedback and the massive 600ton example. So to claim full compliance with the welding code, all these (very similar but) unlisted steel should have its own qualified WPS. If I rephrase my requirement slightly different: On the basis of producing safe & strong welding...

    Asme 9 and AWS D1.1: Mixed group welding & equivalent grouping

    We used a lot of S355J2, St52.3, & EH36 for main structure. We also used A36 & SS400 for non-critical structure which are welded to the main structure. Out of curiosity, I checked into these two welding codes. Only SA36 & EH36 (AWS D1.1) are 'officially' listed in these code. 1) We have WPS...

    Strain response under hydrostatic pressure past yield

    Below is my question: A steel of 200Mpa yield, when loaded to: Case #1) Stress1=stress2=stress3=400Mpa (compress) Strain1=strain2=strain3 = 0.1% -0.3*0.1% -0.3*0.1% (Elastic strain) + A% -0.5*A% -0.5*A% (Plastic strain = no flow = 0) = 0.04% Or 0.08%? (After yield, continue to deform...

    Steel behavior (strain) under hydrostatic pressure past yield

    Hi desertfox, Thanks for the lecture link. I do understand about the point in Mohr circle & non-yielding (for uniform compression). What I am having doubt is on the strain response. Will the cube compressed elastically & infinitely as per calculation ie 0.08% or will it be retarded at 0.04%...
