ADAPTIVE MESHLESS METHOD AND ITS APPLICATION IN THE CONTACT PROBLEM OF THE BIOACTIVE COATING

  • The adaptive meshless methods, which have lots of advantages, such as does not need any mesh information, the nodes can be moved, inserted and deleted freely, suitable for adaptive analysis to achieve high computation precision with a less number of nodes and less computation time for a given error tolerance, are convenient for the complex problems which the finite element method can not or is difficult to solve. The theoretical basis and the development direction of the adaptive meshless method are discussed in detail, based on the strain-energy-gradient adaptive meshless algorithm coupling with the finite element method, the contact problem without friction of the two kind plasma spraying bioactive coatings is analyzed, the distribution of the von Mises stress is given. The result shows that the adaptive meshless model can be applied to the contact problem of the biocomposites.
