Can any one please advice how to calculate number of thermal cycle for below case.(5.5.2.3 of ASME Secv 8 div-2)
Temperature will be varying from 60 deg.C (adsorption) to 280 Deg.C (regeneration) and vessel will be subjected to 1 cycle/day.- Total Life-30 years.
How to arrive allowable stress per ASME Section 8 div-2 based on yield strength and ultimate stress. what is the code reference.
I wanted to use the modified material (by quenching and Hardening),the UTS&YST modified to 105ksi&85ksi , what are the code reference for this??? how much allowable...
can anyone pls clarify below queries about discontinuity stresses:-
Pm-General membrane stress - its because of pressure loading and it is limited to S.
PL-Local membrane stress- what is this stress actually??? and why it is limited to 1.5S
Pb-primary bending stress - what is this??? also this...
Can anyone explain why stress linearization required and how it is doing with ANSYS??
pls suggest any literature for FE Analysis as ASME section VIII Div-2
can one one please clarify when to use Part-5 of ASME section 8 div-2??
part 5 can use directly with out doing any check per Part-4??
or if some component fails in part-4 can we check with part-5???
(for example a cylindrical shell fails per part-4 ,can i check it as per part-5???)
Part-5 can...
Following are the vessel design/construction detail and I wanted to exempt the impact testing of plate:-
can anyone please confirm that whether my understanding of code is correct or wrong??

SR = short radius, 1D
LR = long radius, 1.5D
These are the radius of long/short radius elbow ..whether it is specified anywhere in the standard??
In case of long radius reducing elbow what will be the radius ??
Please help..
