Write out local material orientation

Submitted by reneem5898 on

I have a vibration problem where I have assigned the local material orientation by assigning points a and b. By assigning points a and b, I define one material direction in my local coordinate system - direction 3. From Abaqus documentation, I understand that the other two directions are assigned to be orthogonal to the 3rd direction but are set somewhat arbitrarily. I want to write out the directions so that I know the three vectors defining all three directions of the local material orientation.

I have set up a vibration problem. I assign a local material orientation by assigning coordinates a and b to define the 3rd material direction. From documentation, I understand that the other two directions are assigned to be orthotropic to the 3rd direction. Beyond that, I think that they are set somewhat arbitrarily. I want to output each component of the local material orientation.

Dear Abaqus Experts:

 

I am new Subroutine user and I want to analyze plastic deformation behavior of micro component.

So, I have to link Abaqus,gfortran,and Microsoft Visual Studio.

I tried several methods by reference to the following link,but I have not yet been successful in them.

So, I'm a very necessary help of Abaqus experts.

 

Detail

1) I added the command "mingwvars.bat" to Abaqus Command > right click > properties > target

1073741819 error code in ABAQUS

Submitted by ashkan khalili on

Dear all,

I'm using UEL in ABAQUS. The UEL works perfectly as far as I have 256 time increments (each 1e-6 sec). When I'm trying to increase the time increments (let's say 512 with the same 1e-6 sec per increment) Abaqus gives me error code 1073741819.

I'm running Abaqus 6.14.2 with Intel Fortran Composer XE 2013 on a Windows 7. CPUs are 3rd generation.

I would appreciate if you could help me to figure it out.

Best Regards,

Strain calculation in ABAQUS

Hello,

I have some troubles in calculating the strain in ABAQUS. I have the following Model with one element (see picture) and a linear elastic isotropic Material (Steel), which is sheared in the x-direction. The analytical result of the strain tensor gives me in xz-direction 0.25 (see picture). The result in ABAQUS is 0.5. I ran the same simulation in CalculiX CrunchiX and got the expected strain of 0.25 in the xz-direction

Can anyone tell me how ABAQUS calculates the strain for a linear static analysis? Why is the ABAQUS result exactly 50% higher?

Application of Corotational Formulation

Submitted by Dario Schiano … on

Hello,  I am a PhD student in Mechanical Engineering, and at the moment I am studying the co-rotational formulation from Criesfield's books.

I am looking for applications of the corotational formulation in ABAQUS or MATLAB; my supervisor suggested me it could be done in ABAQUS through a User Defined Element Subroutine, but being a new user to this software I don't really know from where I should start.
