Hi,

 I am simulating ductile fracture through uniaxial tensile test. The material is Aluminum Alloy. Dogbone specimen is simulated to get Equivalent Strain Vs Stress Triaxiality & Equivalent Strain Vs Lode Angle plots. The evolution of Stress Triaxiality & Lode Angle must be 1/3 & 1 respectively over time or with Equivalent Strain. I have marked few time history solid elements in the rupture zone of model. The problem is, Triaxiality and Lode Angle is different for different time history elements.

I have written a introduction manual/tutorial on Abaqus Scripting. I got some good feedback from my colleagues. Therefore, I would like to share the manual.The manual should give a short introduction (it will not take more than one hour) to Abaqus script in Python.

You can find the manual here:

Abaqus Script Manual

Via the same link you can also find more information on the connection between Matlab and Abaqus

Good luck!

WHAT IS THE MATHEMATICAL EQUATION FOR CONSCIOUSNESS ? 

Hello everyone!

I'm a Mechanical Engineer performing a Bird Strike simulation on a Radome using ANSYS LS DYNA.

I'm using ALE Formulation to simulate this but after some minutes of processing, the program says :

- impossible find file batch ansyslsdynaz.bat

- Error for invalid volume on "n" redo cycle

 And some nodes have x, y and z velocity as NaN.

Can anyone help me?

Thanks

I have Abaqus 6.10 and Intel Visual Fortran 11. I want to implement umatmst3.inp and umatmst3.f files in Abaqus Documentation to Abaqus. But I didn't make it. Can anyone help me?
