hello everyone,
Can anyone briefly guide me through how to simulate a bi-axial compression test. Especially the loading part.
Thanks in advance

Re: simulating bi-axial compression test
You need to apply the forces/displacements in two orthogonal directions

Re: simulating bi-axial compression test
Thanks for the response
Yes, that's quite obvious.
I was wondering about how to record the response at each load step
for ex: for uni-axial compression
set load 10
pattern Plain 1 Linear {
load 13 0 0 -$load 0 0 0
load 14 0 0 -$load 0 0 0
load 15 0 0 -$load 0 0 0
load 16 0 0 -$load 0 0 0
load 17 0 0 -$load 0 0 0
load 18 0 0 -$load 0 0 0
}
set stepSize 0.1
set numSteps 100
integrator LoadControl $stepSize
analyse numSteps
Will this work for 0.1 load increment as time series is linear with default 1 load factor.
Thanks again
