Abstract:

Model and full-scale acrylic windows in the form of spherical shell lenses with parallel convex and concave surfaces have been imploded by loading their convex surface hydrostatically at a 650-psimin rate while their concave surface was exposed to atmospheric pressure. The thickness of the model windows varied from 0.250 to 1.200 inches and of the full-scale windows from 0.564 to 4.000 inches, while the included spherical sector angle of the lens and the bevel angle of its edge varied from 30 to 180 degrees in 30-degree increments. The low-pressure face diameters of the model windows varied from 1.423 to 5.500 inches, while those of the full-scale windows varied from 6.200 to 35.868 inches. In addition to critical pressures, displacements of the lens under hydrostatic pressure were recorded and plotted as functions of pressure. Author
