    摘要: Vehicle arresting beds, for installation at the ends of aircraft runways, are effective to safely decelerate aircraft entering the bed. The arresting bed is assembled of a large number of blocks of cellular concrete having predetermined compressive gradient strength, so that aircraft landing gear is subjected to drag forces effective to slow a variety of types of aircraft, while providing deceleration within a safe range of values. An arresting bed typically includes an entry region of a depth increasing from 9 to 24 inches formed of blocks having a first compressive gradient strength. A second region, which may be tapered into the first region and increase in depth to 30 inches, is formed of blocks having a greater compressive gradient strength. An aircraft thus experiences increasing drag forces while it travels through the bed, to provide an arresting capability suitable for a variety of aircraft. Arresting bed systems may include composite blocks including portions of cellular concrete of different strengths, reinforced blocks including a lower layer or grid of higher strength material, and cellular concrete block edge members surrounding a bed of aggregate or poured in place cellular concrete.

A protective hardcoat layer of cellular concrete of strength greater than the blocks overlays the blocks to enable service personnel to walk on the bed without damage. Arresting bed systems may be provided in alternative configurations, such as a bed formed of an aggregate including pieces of cellular concrete with or without interspersed pieces of other compressible material and covered by a hardcoat layer.

    摘要: Arresting material test apparatus, test probes and test methods enable testing of compressive gradient strength of cellular concrete, and materials having similar characteristics, on a continuous basis from the surface of a section to a typical internal penetration depth of at least 60 percent of thickness. Previous testing of cellular concrete typically focused on testing to confirm a minimum structural strength prior to structural failure or shattering of a test sample. For an aircraft arresting bed, for example, cellular concrete must exhibit a compressive gradient strength in a relatively narrow precalculated range continuously from the surface to penetration depth equal to 60 to 80 percent of sample thickness. Precalculated and controlled compressive gradient strength is critical to enabling an aircraft to be safely stopped within a set distance, without giving rise to drag forces exceeding main landing gear structural limits. New test apparatus, test probes with post-compression build-up relief and test methods are described to enable such testing and recordation of data showing the gradient of compressive strength as it increases from the surface of a test sample to a predetermined depth of penetration. Resulting compressive gradient strength data is representative of performance of cellular concrete sections in decelerating an aircraft.

    摘要: The propagation of a crack from the surface of the dielectric layer of an integrated circuit, through to the underlying circuit elements, is prevented by controlling the interface between the outermost, dielectric layer or layers and the inner layer or layers of the integrated circuit construction. The interface is weakened so that a crack that encounters the interface is caused to propagate in a horizontal manner, along the interface, preventing propagation of the crack in a direction that would be harmful to the manufactured article. This is preferably accomplished with multiple layers of material, each of which is made capable of redirecting (deflecting) the crack. Deflection of the crack, and arrest of the deflected crack along the interface, is made possible by controlling the fracture resistance of the interface.
