Horizontal Vessel Support

Hellow colleagues

I'm an equipment designer and i need to verify the stresses on the shell of an horizontal vessel over 3 saddles. I don't want to make a FEA analysis because is quite expensive to me.

I ask for your colaboration to find a method, other than Zick's one (only applicable for two saddles), to calculate the stresses on an horizontal vessel over multiple saddle supports.
I'll appreciate if  anyone can suggest me some reference articles or bibliography.
Thanks
Martin

to model creep behavior in ABAQUS

creep

Hiya,

I have different stress strain curves at different hours (1hr, 10hr, 100hr).  for a constant stress, the strain increases with increase in number of hours(creep)

They look like stress-strain curves at different strain rates.

now I want to define a material card with these curves with above mentioned number of hours.

I kindly request you to suggest me a CARD in ABAQUS which takes care of this behavior.

Thanks a ton for your help, in advance !

initial strain

Hi everybody,

 i?m simulating a manufacturing chain finite elements analysis. Every step of this chain have been developed by different software. I use ANSYS. Somoone know how to impose the initial strain and stress state deriving from previous simulations to my ansys model: I'm able to use INISTATE command but only stresses are imported, I loose initial strain info: are they important if my material is elasto plastic? how i can resolve the problem?

 

Thanks in Advance Michele
