Sažetak
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 the mixed paradigm does not lock because the Kirchoff-Love conditions have to be satisfied only at the nodes. The validity of the theoretical predictions is supported by the presented numerical examples, where good convergence and accuracy is obtained even if the low-order meshless approximations are used.
