Elastic Sliding between two contact surfaces
Altair EmployeeHi together,
i would like to connect two surfaces of two different parts. The contact should be able to slide transverse (with a specific Stiffness).
Is there an option to define this transverse stiffness in the PCONT options. Can i define it over Mu1? I am just wondering because Kt is calculated with the Equation Kt = Mu1*Stiff and Stiff is only a relative? Or is there any other way to prescribe a specific stiffness to the contact (and transverse)?
Do i have to enable the option FRICESL to enable the sliding?
Thank you for your help!

Thanks again!
So if i specify a sliding distance in FRISCEL of 5 mm the frictional force will grow linear. But at what slope? The transverse stiffness?
What happens if the sliding exceeds those 5 mm? Or is the friction force at 5mm slide increased, so that the sliding distance can t exceed this value?
Hi Sebastian,
You ca provide stiffness using STIFF_REAL_VAL on PCONT.
Ofcourse Mu1 affects the transverse stiffness KT. You can include FRISCEL>> AUTO this may help enable sliding.
