The stability of uniform-friction piles inhomogeneous and non-homogeneous elastic foundations

The stability of piles that are supported vertically by a frictional force and laterally along their entire length by an elastic Winkler foundation is investigated for the case when the coe.cient of subgrade reaction is either constant or varies linearly with depth and the friction is constant along the embedded length of the pile[ A comparison between frictional and end!bearing models is made[ Finally\ a concise summary of the buckling loads for fully embedded friction piles is produced
