Sažetak
The mixed Meshless Local Petrov-Galerkin (MLPG) collocation method is applied for solving problems in gradient elasticity. The mixed collocation approach is utilized to lower the continuity requirements of the approximation functions in the numerical model and improve its numerical efficiency. The method utilizes a staggered solution procedure, where the original gradient elasticity problem is solved by solving two successive sub-problems governed by the second- order differential equations. Furthermore, two different staggered procedures are applied. Thereby, the solution of the first (classical) sub-problem is used as the input for the second (gradient) subproblem. Special attention is dedicated to the utilization of appropriate natural boundary conditions in the gradient subproblem. The proposed procedures are tested by the problem of a rectangular plate with a crack, where obtained numerical results are compared to available analytical solutions.
