Consistency of Von Mises Units?

[GhostRyder]

if force, F is in in.lbm/sec^2 and area, A is in in^2, how does mechanica get Von mises in lbm/sec^2/in^2? All places I've looked say, for example, 2.7E4 lbm/sec^2/in^2 is equal to 27ksi. can someone walk me through this please?

I came across this problem, you should change your unit system in Pro/E from default to IPS first, then all unit will be changed from lbm to lbf, whatever this is force or stress.

Hello GhostRyder,

Take a look at the out put window again: It should
read (in lbm/sec^2/in^2).

What it is saying is this:

in*lbm/(sec^2*in^2) which is:

lbm/(sec^2*in).

Good luck,

Steve
