defect analysis in a blade and measures to mitigate it using nontraditional optimization technique

In this paper, defects caused in casting process are identified, analyzed and minimized by obtaining the suitable remedial measures. Defect analysis using Non-destructive Testing (NDT) is an expedient way for controlling defects in Mechanical and Aerospace Systems. Defect Analysis means identifying, locating, interpreting, evaluating and generating corrective and preventive actions.
