hi,
i need to find to contact shear stresses and pressures between two surfaces while surface vibrating on eiganfrequencies.i tried many times using frequency step with interaction but everytime i ended up finding every contact value zero.
is there any way i could find contact values with eigenfrequency?
thanks a lot!
