Abstract (en)
In this article authors present a new strategy for displacement solution calculation near singular points. Solution improvement in singularities is achieved modifying physical coordinate matrix used in least square problem equations: instead of the standard quadratic polynomial a new polynomial with singular elements is taken. Proposed algorithm is incorporated to the adaptive finite element analysis and tested with different mesh optimality criteria. Numerical examples demonstrate the advantages of the proposed algorithm.
