How can I apply an enforced displacement of 10mm/min on a node for a lapshear simulation?
Dear all,
I've created a lapshear model to analyse the adhesive, which connects the two sample sheets. Now, I want to apply an enforced displacement on one sample sheet by SPC. The enforced displacement should be 10mm/min.
As far as I know, the enforced displacement has the unit [mm] by default. How can I apply the 10mm/min loading on my model?
Thank you very much and regards,
Stephan

Hi Stephan,
You can use IMPDISP card to apply prescribed displacement varying with respect to time using a curve.
Below is the keyword manual help:
Hope this helps.

I forgot to mention that I use Optistruct for the simulation.
Hi Stephan,
I guess here you are interested in Transient analysis as in a regular static analysis, the physical time is not considered.
In case you want to conduct a nonlinear transient analysis, you need you input your velocity under the TLOAD1 entry (Load type = VELO). Of course, you will need to convert the velocity in a consistent unit system (like mm/sec if your model is in mm, MPa, ton, sec).
There is a tutorial about nonlinear transient with velocity input in our documentation here.
Hope this helps.
Thanks,
Omar.
