| Abstract: | cubic polynomial splines are used for computing approximations to the solution of a system of fourth order boundary-value problems associated with obstacle,unilateral,and contact problems.mesh points are taken at mid knots,adding boundary equation,using the method solve the numerical example exited in other paper.It is shown the method gives efficiency,whose applicability and superiority over other splie,finite difference method. |
| Keywords: | cubic polynomial spline boundary-value problem obstacle problems variational inequalities |
