unit for force always N?
unit for force always N?
(OP)
Hello,
if my basic units are different from kg,m,s, am I still allowed to use N (Newton = 1 Kg*m/s²) for forces (loads) ?
or should I adjust the unit for my forces accordingly (i.e. g*mm/s²) ?
many thanks, Alex

i.e. Force in N, length in mm = Stress in N/mm^2
Force in kN, length in mm = Stress in kN/mm^2

..assuming that you are using SI units of course

because I have thermal prop. like thermal conductivity in J/(s*mm*C) and density in g/mm³.
So my forces should be expressed then in g*mm/s² which corresponds to 10^6 N!!!
In the Abaqus docum. Newtons come up with E modulus and mechanical loads.
my question: can I use g*mm/s² (which is coherent with my basic units) instead of N, everywhere in my simulation? (of course then I would have stress in g/(s²*mm) )
Many Thanks, Alex
