The investigation herein is<br>conducted on the condition of shape function by which exact solutions may be reproduced at the nodal points<br>regarding to a few number of elements. The examined shape functions which satisfy the homogeneous<br>governing equations in elastic and plastic soil through bisection iterative algorithm are introduced to obtain the<br>so-called exact element stiffness matrix via total potential energy principle. Numerical examples of elastostatic<br>pile embedded in elasto-plastic Winkler foundation illustrate the accuracy of proposed element compare with<br>conventional finite element shape functions. Axial force and displacement solutions show very good agreement<br>with data from the available literature i.e. the exact nodal displacement solution is obtained correspond to any<br>point load level even with a single element mesh employed.<br><br></p>}, number={31}, journal={GEOMATE Journal}, author={Chinnapat Buachart and Chayanon Hansapinyo}, year={2016}, month={Dec.}, pages={147–152} }
