2. Opposite sides of a rectangular plate are displaced at v and fastened. The plate contains a central crack parallel to fastened sides. How K, changes if the crack length increases? How the parameter B = H/W may affect the character of the dependence? Consider also limiting cases - of the infinite strip with a longitudinal crack at W +00; - of the infinite strip with a transverse crack at H+, v/(2H) + 50; - of the infinite plate at W 700, H +00, v/(2H) +€0. Compare with the case when stresses are aplied Сравнить со случаем, когда к краям платины приложены напряжения так, что в отсутствии трещины были бы растягивающие напряжения 00. George C.
