Hello,

I am trying to simulate a tensile test on a NL material in Mechanical APDL. I'd like to have multiple substeps on the transition linear-nonlinear zone, so I divided the imposed displacement into 2 substeps: [t: 0.0, u: 0.0; t:1.0, u: 0.5; t: 3.0, u: 1.0]

My problem is that the first 10 substeps of the second load step are fixed at u=0.5. How can I solve this?

Attached below, the Code I'm using and the results I get from Ansys (I'm using a linear material in this simulation) :

You are solving for time=2 without changing the load. So the load stays at 0.5
Instead, for load step2, set time to 3
define your load and solve
!load step2
time,3
DCUM,....

Or consider defining a table to apply the load
