ABAQUS

We just can't bottle up this exciting story...

Hello,

I am using Concrete Damaged Plasticity model. My parameters are correct but I am not able to get the desired stress-strain curve for my model.

Can anyone help me with how do I plot the stress strain curve for it (Nominal Stress vs Strain, Reaction force vs displacement or anything else)?

I want to know the exact procedure to do it.

Thanks in advance. 

Dear friends, i current doing a project work on testing fatigue life of superelastic nitinol. And since i am very new in using abaqus for testing the simulation, i seeking help from people around here to ask for method to test the work. My objective is to set a maximum elongation for 1%-6% of elongation and test for 40,000 cycle if it can work for this amount of cycle..

i Hope anyone can help me as i need to finish this project in order to graduate and i didnt get any single help from regarding this software from my side..

Hi all,

Hi mechanicians:

I decided to post because I have an inconvenience that is not shown in other posts.

I am working in the Abaqus - Fortran environment in a thermal analysis. After implementing a new procedure (which actually works), the .sta file shows me that it has problems in its unique step, more or less in the 60th iteration (it is supposed to get until 500). Twenty iterations after that gets into interruptions because the code cannot converge.

With these lines it is easier to understand my point:

What do
Guitar Strings Have to do With Dynamic Response?

Tightening
guitar strings to change the sound uses the same principle as tightening head
bolts to change the dynamic response of an engine block assembly. This is
stress stiffening and it affects the dynamic response of a structure. One of
the fundamental components in assessing nonlinear static stress is stress
stiffening, but it is also the most overlooked when evaluating the steady-state
dynamic response of engine assemblies.

In using Abaqus 6.12 XFEM software is there a field output request that can be specified to track the location of the crack tip as a crack grows through time?

Hi every body

My thesis is about ship grounding. In this phenomenon, ship hit a rock. I can simulate this problem in Abaqus/Standard,without wave effect. But in reality there is water and waves. Can I simulate this problem with ABAQUS? Is it possible to define water(or wave) aruond ship and rock?

Hey all,

I am trying to apply an Electric Potential B.C. to a surface. I want to use the dynamic/explicit analysis type, however, when I select that as my step type, the Electric Potential B.C. option disappears from the edit B.C. window! Is that due to a license limitation or an error I might have made in one of the definitions?

Thank you!

When designing a permanent magnet machine, one of the most fundamental and difficult goals is to reduce the cogging torque curve. The challenge in reducing the cogging torque is to also decrease the numerical noise generated by the mesh. Finite element analyses and the advanced meshing functionality that is available through Abaqus/CAE allows for a faster and more accurate prototype.

I've modelled a DCB specimen and applied Boundary conditions and load... I followed the same procedures given in abaqus documentation... As expected the crack initiates and propagates along the interface... I can get the Resultant force vs displacement plot from the analysis.. But i dont know how to plot the fracture toughness vs crack length plot in ABAQUS..

Please help me... Your suggestion would really help me a lot..

The PDA model implemented in Abaus is an implementation of the idea of the cohesive zone model (CZM), which is quite popular for the analysis of delaminations, but PDA is for intralaminar damage. The problem my group faced when trying to use PDA was "where do we get the material parameters?"  We asked around in blogs and such but could not find a definitive answer. So, we went to work and came up with a methodology that may serve you.

New textbook includes an explanation of the concepts involved in the detailed analysis of composites, a sound explanation of the mechanics needed to translate those concepts into a mathematical representation of the physical reality, and a detailed explanation of the solution of the resulting boundary value problems by using commercial Finite Element Analysis software such as Abaqus.

Hello,

I have an Abaqus 6.12-3 installed on a Windows 8 64-bit system.
Everything works smoothly. I am easily able to take control of the CAE
and model, define loads, steps, sections and jobs. The problem is while
running the jobs. The job aborts splashing an error "Unable to change
the current working directory to
C:\Users\ANIABU~1\AppData\Local\Temp\Ani Abu_I-beam_3876." This happens
with all the jobs. Rarely does the job complete successfully, but I am
unable to understand the underlying procedure. I did not request any
