Information × Registration Number 0205U000832, 0103U000280 , R & D reports Title Working out methods of optimization of stress condition of anisotropic plates weakened by crocks and holes. popup.stage_title Head Shvabyuk V.I., Registration Date 14-02-2005 Organization Lutsk State Technical University popup.description2 The methodology of calculations of deflected mode of anisotropic flexible plates, slackened by the systems of holes and cracks, is worked out; the method of defining the holes of optimal form with the minimal level of tension concentration is developed and its effectiveness is demonstrated by examples; the algorithm of calculations of quasi-static process of cracks spreading along the arbitrary curvilinear trajectories in anisotropy plates is worked out, its effectiveness being illustrated, and the question of stopping or slowing down the crack movement is investigated.
