A-star Mesh Based Initialization Algorithm for Functional Iteration and Newton-Raphson Procedure in Acoustic Emission
Original language description
Acoustic emission is a non-destructive testing method detecting and identifying the defects that are generated by elastic waves in a solid body under stress. Finding geodesic surface curves is the essential task for the acoustic emission source localization. The aim of the internship is to find accurate geodesic curves on surfaces for acoustic emission. The computer programmes have to be quick and efficient. First, we focus on the A-star's algorithm to find a path between a start point and an end pointthrough the mesh on the surface considered. The drawbacks of this method and several improvements are presented in this paper. This approach provides us with the correct surface path but it is not accurate enough, thus the path is consequently used by other numerical methods called Functional Iteration and Newton-Raphson method. These two iterative methods use the theory of geodesic curves and provide good results in terms of accuracy and computational time.
