to model creep behavior in ABAQUS

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 !

How to calculate natural frequency of a beam with 3 spans

We are designing a underslung crane with 4 end trucks (3 spans). The crane girder is made of Universal Beam (UB). Can someone help to calculate the first fundamental (natural) frequency of the beam?
Thanks

Abaqus for Backplate of drum brake

Hi..

 Anyone here could help me out as to how to use abaqus for analyzing the back plate of the drum brakes??

and also.... please give me some website where in i cud get some tutorial stuff for abaqus. im starting to learn abaqus.

 thanks.

Initial stress and strain in ANSYS

Choose a channel featured in the header of iMechanica: 

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

Centrifuge Reliability Problems is solve

2007-10-12

Centrifuge is a machine that spins
at a high rate of speed to separate solids from a liquid. The big problem with
the Centrifuge equipment is its reliability. Conventional centrifuge designs are
often break down in brusque industrial environments and which can affect the
whole assembly line operations. So many industries try to avoid the use of
centrifuge equipment. This problem of origin is lies on the relationship
