Bending simulation in Kangaroo

Hi Andrea, I'm afraid I don't know how to get this physically correct. However, I've found that what matters most in simple tests - like the one above - is the relation between Bend Strength and Spring Stiffness. Stiffer springs give more exact bending curves, but take much longer time to settle. Good luck! /Mårten

Hi Mårten,

How do you calculate physically correct values for Kangaroo BendStrength?

For rectangular shape I assumed to use this formula:

• F is the load (force) at the fracture point
• L is the length of the support span
• b is width
• d is thickness

Is that correct? (or should I use the EI of the material?)

 

Thanks.

 

Andrea
