peridynamic-pmma material

dear Riccardo
I use 0.0015 for horizon and amount of force was lower than the previous value. But I can not get the exact amount of force.

thanks for helping me


I see that you are using a value of c = 2.32251482e19 for the stiffness/volume of PMMA. Isn’t that value supposed to be something of order of magnitude e22?
What density are you using?
