Hi Bruno,

I'm still confused.  When two spheres are in contact, I suppose there
must be a normal stifness and a shear stiffness(though it may equal
zero) between them, regardless of the IPhys and Law functors.

My idea is to change some parameters in the material class to enlarge
the shear stiffness between the spheres. And I thought "poisson" is a
factor. If changing "poisson" does not lead to the change of shear
stiffness,  then what paremeters should I focus on to achieve my goal?


Thanks!
Shenyang
