Nevertheless, in these approaches the contact intethee are charactered sboly ed stiffeess k. and k. " which is not perfect and rigorous in thc vitw of solid mechanics and rather rough for the description of the behavior of the idtfores. in collbet, taken as a contact problem, the principal chatrs of the idtcthees can be reflected : ( l ) the cbntact inifore is of shear strength which implies tha a generic pair of contact points on the inidse will displace coincidentally if the tangential fbrce at this point has not reahed the 1imit resistance, else, relative s1ide betwee the points will occur along the tangental direction. ( 2 ) no matter the relative slide occurs or not, the contact bodies cannot invade each other in any wise
