Hello,
Is there anyway i can calculate and plot the tangential stress in Abaqus directly. I know we could do it manually in sense , calculate s11, s22, s12 and then calculate tangential stress in excel. I would like to calculate and plot tangential stress around the circular cutout shown in the document attached.
I would be really glad if someone could give me tips on this.
Thank you,
V Manneth
Does anybody have this paper?.

Dear all,
in order to access the last value of my state variable SDV at specific integration points and specific elements, I need to write the SDVs into .fil file in order to be able to read them inside my UMAT at each time increment.
I use the subroutine DBFILE to read the .fil file; the keyword to access the state variables is "5", but I don't know how I can go to the value which has been already written to the current integration point.
Could anyboby help?
Thanking in anticipation,
hadi

Is there anyone familiar with the S-N curve when dealing with Fatigue test?
S is the stress,σ? For a specific load, isn't it some stress distribution in the test coupon? How do somes testbooks or some industrial standards use only one stress as an element to describe the material or some metal products' fatigue strength? I executed the fatigue test for some metal-products by the load-controlled servo-hydraulic tig. I have some (load,life)points on the S-N coordination,e.g.(7.2KN,258910cycles),(6.0KN,10000000cycles) .

We know from fracture mechanics theories that fracture instability in a perfectly brittle material occurs when energy release rate (G) becomes equal or more than two times the surface energy (γ) of that material. The value of G = 2γ is known as fracture toughness Gc. This is the classical Griffith criteria of brittle fracture. Experimentally, however, we know that plasticity becomes eminent for most materials and this criteria does not work.
The day before yesterday, Mar. 14 (3.14), was a great date, because Albert Einstein was born at the same day 130 years ago.
I and my wife enjoyed a very good holiday that day in Taipei. Most interestingly, we found a vivid statue of Einstein made by Ju Ming, stood still in front of the Chen-Ping (eslite) bookstore.
We took several photos around this statue. Here I share one of them with you.
Hi everone,
The new version of ABAQUS/CAE 6.8 seem to have capability of automatic failed element removal. Does any body has any experience about this new feature in ABAQUS.
cheers,
