Dear guys!

I've a qustion about system of units in abaqus!

I thought that the system of units in a model must be the same but in abaqus example "stiffened plate under the blast load" in define the material the density defined in "kg/m^3" but other properties defined in "Pa"!

Is that true? if yes why?

Hi
I need urgent for an artice in the  journal of applied mechanics,ASME(an old issue--> December 1959).My requested article is "Piping Flexibility Analysis"  by L.H. Chen
Is there any one has this issue?

Sincerely yours

Hi

I am a beginner in working with Abaqus(v 6.3),I want to model a simple piping system,I use pipe and elbow elements,in section assignment, I select a beam section for the part .But When I run the job,an error occurs due to element properties in section assignment,when I use beam element instead of pipe there is not such an error in job-run.
but I want to use pipe and elbow elements...what can I do to solve this problem?

any help is appreciated

2.The Interaction module

I am trying to built a model for a laminated angle-plied plate, which has different fibres orientation in each plate. But I have a problem in materilas property as the Abaqus told me after analysis andmake error. The error is that the properties of the model in not assigned well. I have assign them as shell composite and make the local co-ordinate orientation.

I have tried to use homogeneous material and enter the Engineering contants in all directions and by just changing the local axis orintation, it works. But I don't know if this is right or not.

Need advice plz

What's a general relation between dislocation density (scalar) and plastic strains (tensor) in 3d? any references? thanks.
