Material properties for concrete

Hello I have started using the karamba plugins to visualize buckling from my concrete pieces but I have some doubts about how can I apply some parameters.
First thing is that i dont know what does “valuetest” numer to the young modulus and to yield strengh, what is its function.
And on the other hand, i want to know how can I add the open time between layers, i mean the time that my material needs to cure.

Hi you can refer to this example on a guide to input concrete materials for 3d printing Buckling Simulation for 3D Printing in Fresh Concrete - Karamba3D

Yes the screenshot i have post is from that example, but i dont know what ‘variable testvalue’ means in the formula

There is a video that presents the research and the script
Buckling Simulation for 3D Printing in Fresh Concrete (with Shaun Wu) on Vimeo

yes but i doesnt explain it :frowning:
