Hello
I have problem with unit system in abaqus. I have already checked tables and discussions about this subject in internet and I am confused and looking for Numerical example.
Could you please give me example of unit system in abqus. For Instance, Imagine I have model with mm and these are the property of material
E= 1.85 GPa
G=0.56 GPa
tn= 21.63 MPa
ts= 17.9 MPa
Gic= 0.43 [N/mm]
Giic= 4.7 [N/mm]
I made my model in mm, I know young modulus should be MPa. So my Question is that shall I write:
1850 or 1.85e6 in the box
21.63 or 21.63e6
Could you please give me figures that I should write in the property box
Thank you
Thank you for your response, but as i said i checked all information related to Abqus unit system. So, I am not looking for PDF file here.
Hi
Look, firstly choose your system of units, si or mks or imperial or anything. If you chose si you should define your forces with newton and lengths with mm. Abaqus can't recognize giga or mega or other prefixes. So write them in number format and you'll get your answers the same way. Good luck.
If all your dimensions are in mm, then you should convert the material properties to N/mm2 (which is the same as MPa). Hence for your example where E = 1.85 GPa, you should type 1850 or 1.85e3 (which is the same as 1850 MPa or 1850 N/mm2) in the box and where tn = 21.63 MPa, you should just type 21.63.
On the other hand, if your dimensions were in meters (m), then you need to convert the properties to Pa (which is the same as N/m2).
The noteworthy point here is CONSISTENCY.
Hope that answers your question, let me know if you have any other question(s).
