software

hey friends,

i am using abaqus 6.9-3 on win7. i need to use *nodefile command in the input file. But when i run the file through GUI it says:

WARNING: The following keywords/parameters are not yet supported by the input file reader:

---------------------------------------------------------------------------------

*BOUNDARY, LOADCASE

*NODEFILE

Please help me.....

also i wud like info on running jobs through command prompt. I have no idea about this.

I have added commands directory to system variables......

Hello

I need to simulate a simple bar under uniaxial stress, spliting it into 2 pieces , in fact i need a tutorial or a sample test to see the whole process.

i know a little about ductile damage and related issues but it doesnt work for me , so i need a simple tutorial

Thanks

To eliminate the unwanted axial strain constraint, in Abaqus the stretch dL/dS at the node of each such element is taken as an internal variable, local to the element (a third internal node is created for this purpose, and so it is not shared with neighboring elements.) 

Above paragraph is excerpted from chapter about Euler beam theory in ABAQUS theory manual.

This is a free tool to simulate the fragment of brittle materials. You can use it to calculate the fragmentation of some differernt materials with different weakened styles. Also you can use different model to analyze your fragment process. The tool and its introduction are showing the attachment.

Hello All,



I have written a user material behavior using VUMAT for hyperelastic materials.



I am validating VUMAT on a flat square plate.



1. The plate is subjected to uniaxial loading.

2. It has 4 structured quad elements.

3. One side of the plate is fixed and the opposite side is subjected to shell edge load.

4. The element is of type S4R.
