Abstract: The paper summarizes our recent work in the development of practical algorithms for the automated mesh design in finite element stress analysis. A regional mixed mesh improvement procedure and a regional mapping procedure are considered. The error control, algorithm implementation, code development, and the solution accuracy are discussed. Numerical examples include automated mesh designs for plane elastic media with singularities. An extended application of the regional mapping procedure is to incorporate the mesh design for moving singularities. An efficient moving mesh region to handle stress and displacement discontinuities due to a moving force passing through a plane media is presented in a numerical example as an illustration.
