THE MESHLESS MANIFOLD METHOD FOR 2D CRACK PROBLEM
The meshless manifold method based on circle covers consists of the partition of unity method and the finite cover approximation theory. The method provides a unified framework for solving both continuous and discontinuous problems. In the method based on circle covers, two cover systems are employed. The mathematical covers system provides the nodes for forming finite covers of the solution domain and the partition of unity functions. The physical covers system describes geometry of the domain and the discontinuous surfaces in the domain. The shape functions in the method are derived by the partition of unity and the finite covers approximation theory. The approximation functions and the equations of the coupling method are developed in detail in the paper. The validity and accuracy of the meshless manifold method are illustrated by numerical examples.
