Abstract

A class of collocation methods based on B-spline approximations is proposed for solving equations of linear elasticity. Methods can be easily implemented and provide a high order accuracy at low cost due to the nature of both B-spline approximation and collocation method, in which B-spline approximation can be generated by some classical recurrence formulas and no integrals are involved in the calculation. Methods are examined for two examples. Some direct and iterative algorithms for solving the B-spline collocation systems are discussed.
