    On Shear Locking in MLPG Solid-Shell Approach

    T. Jarak1, J. Sorić1

    CMES-Computer Modeling in Engineering & Sciences, Vol.81, No.2, pp. 157-194, 2011, DOI:10.3970/cmes.2011.081.157

    Abstract A solid-shell MLPG approach for the numerical analysis of plates and shells is presented. A special attention is devoted to the transversal shear locking effect that appears in the structure thin limit. The theoretical origins of shear locking in the purely displacement-based approach are analyzed by means of the consistency paradigm. It is shown that the spurious constraints appear in the constrained strain field, which lead to the appearance of shear locking and sub-optimal convergence rates. The behaviour of the mixed MLPG approach in the thin limit is also considered. It is determined that in More >
