Hi dear all
I don't underestand why in all examples in under commend -T $matTag , -My $matTag and -Mz $matTag have uniaxial Material Elastic equal zero ?
uniaxialMaterial Elastic 1 137520
uniaxialMaterial Elastic 2 0.0
element flatSliderBearing 1 1 2 1 250.0 -P 1 -T 2 -My 2 -Mz 2 -orient 1 0 0
thanks

Re: Mz $matTag
It's because bearings are very flexible in the rotational direction, zero resistance in torsion. Although I don't know assigning zero would create any problem in inversion of stiffness matrix. I would assign very small values.
