Acrylic Plastic Spherical Shell Windows Under Point Impact Loading

Abstract: Acrylic plastic spherical shell sector windows with 117-deg included angle and outside radius of 24-in. (61 mm), have been impacted at their center, with a 12,500 lb (5662 kg) weight, in a simulated ocean environment. Velocities of impacts ranged from 0.205 to 10.702 ft (0.06 to 3.26 m) per second. It has been found that fracture of windows is initiated by tensile stresses on the concave surface of the window, directly below the point of impact. Compressive stresses, generated by external hydrostatic pressure,… Show more

“…Geometries presently investigated include long, thin, straight and curved rods [1], spheres [2][3][4][5][6][7][8], thick spherical shells [9], bars with transverse discontinuities [10] and hemispherically-ended rods loaded at their plane end [11] (the latter paper also includes an account of the quasi-static behaviour of such rods). This earlier work concentrated on the damage observed at the distal (i.e.…”
