Inspection - Hole shape optimization of a lower wing panel based on geomatric boundary shapes / Wahyu Kuntjoro and Zon S. Hernedhi

Most structural design optimization jobs deal with finding the optimum size of structural components. Non-linear mathematical programming techniques are normally used to optimize this sort of problems. Some problems need not only optimum component size but also optimum shapes. Change of shape can be...
