| Abstract: | AbstractThe presence of cutout in structures may result in strength degradation due to alteration of load lines around the cutout. The effects of these cutouts on stress field should be studied carefully while designing of any material. This article presents the optimum design of an infinite orthotropic plate weakened by complex cutout using a genetic algorithm where cutout orientations and fiber angles are considered as design variables. The stress concentration factor is used as fitness function derived using the Muskhelishvili’s complex variable approach for various in-plane loadings. The effects of cutout orientation and fiber angles on stress concentration are discussed. |
