Allowable Stress Amplitude in ASME BPVC Code Section VIII Div. 2

Submitted by Francis J Mammi on Fri, 07/25/2014 - 19:49

In ASME BPVC Code Section VIII Div. 2

Primary menbrane + Bending stresses + Secondary Stresses + Peak = Sa

What's the relationship between the above Sa and the Stress Amplitude in Fatigue cycle curve? Is that a 1:2 or a 1:1 ratio?

Any comments will be appreciated.

how can enter the effect of friction in crack surface in abaqus

Submitted by aapaaapa on Fri, 07/25/2014 - 17:53

Hi everyone,

I want to model friction in crack surface and investigate the effect of it in my modeling. I want to do it in abaqus.

thanks.

Imperfection in a Riks Analysis (ABAQUS)

ABAQUS

Eigen Buckling; Nonlinear Buckling ;

I am performing a nonlinear post buckling using Riks method. I went through different tutorials for the same. I happen to see that an *IMPERFECTION is introduced while performing the non linear buckling analysis.Why is it done? How does/will the model react differently if the Imperfection is no introduced?

I wish to plot the graph of load v/s displacement for 1,2,3,4...10 times the critical buckling load during the post buckling analysis (Riks method). How do I do that?

modeling analysis of microstructure phase transformation in an alloy

Submitted by aapaaapa on Fri, 07/25/2014 - 06:45

Hi every one,

I need to modeling a thermal analysis of a microstructure of steel or other alloy by FEM or XFEM. so i need some metallurgical data for phase transformation.for example at which temperature or time martensit converts to austenit or etc. I also need how I can model this microstructure in abaqus that has change in boundries due to phase transformation. i appreciate if someone help me.

thanks
