Abstract: | The incompatible numerical manifold method (INMM) is based on the finite cover approximation theory, which provides a unified framework for problems dealing with continuum and discontinuities.The incompatible numerical manifold method employs two cover systems as follows.The mathematical cover system provides the nodes for forming finite covers of the solution domain and the weighted functions,and the physical cover system describes geometry of the domain and the discontinuous surfaces therein.In INMM,the m... |
