Boundary locking induced by penalty enforcement of essential boundary conditions in mesh-free methods. (English) Zbl 1159.65361
The authors explore the boundary locking, induced by the penalty enforcement of the essential boundary conditions in mesh-free methods. A remedy is proposed to solve the problem of the over-constraint phenomena. The theoretical explanations are justified through various numerical tests.
