Pro/Mechanica Units For Stress

[UnclePinchPenny]

When I do an analysis for stress on a part it gives numbers but no units. What are the units if in (mmNs)?

 

[roshan]

mmNs stands for MKS units.

mm-millimetres

N-Newton (MKS unit for force)

s-second



This should make it clear:

The MKS unit of force, the newton, is the force which accelerates a mass of one kilogram at the rate of one meter per second per second.

The units of stress in the mmNs system are N/mm2 (millimeters squared) which is also Megapascals (MPa). 1 N/mm2 = 1 MPa. Therefore in your results, you may have numbers for stress like 5e+02. This is 500 MPa.
