Scale of linear static output

[oso]

I am do a linear static analysis using 100 N. If I want to know the displacement and stress for 10 N, Can I just scale down the stress and displacement?

How accurate is the scaled result?

Hai,

Finite element software gives exactly proportional results for linear static analysis.But it mayn't behave so in real life.

Thanks, E.logesh:

Does linear static give proportional results for displacement only? or on all results such as stress, strain, etc.

Best regards.

oso,

All results are linear (for the same node). In fact it is very common when doing a linear elastic analysis (small displacements) to use a unit force and scale the results.
