How to implement Macro-scale dyanmics simulation with adhesive and cohesive failure?

It's my first question here about physics. I would like to ask about the macro-scale physics (the governing equation) needed to implement a dynamics simulator with adhesion and cohesion. Consider the ...

Deformation and Adhesion with Particle Contact Time During Impact

Let's say I have a spherical particle impacting a large flat target (let's say it's a half space) at high velocity. It seems I can approximate contact time during impact by dividing impact velocity ...

Is it possible to eliminate Van der Waals interactions?

I came to know that the friction force actually depends on the surface contact area due to weak interactions (adhesion due to Van der Waals forces) between the atoms of both materials increasing in ...
