Abstract

The extensive use of reinforced duralumin sheet in aircraft construction makes it desirable to know the behaviour of such structures under load. This paper deals principally with the experimental results obtained by testing a large number of reinforced panels of various lengths under direct compression.

The main purpose of the investigation was to determine the ultimate stresses in the reinforcing members, which in this case were bulb-angles of a size commonly used in aircraft constrution. It was, however, felt that it would be desirable to obtain as much information from the tests as possible. Consequesntly the stresses in the bulb-angles were measured at intermediate loads for a number of panels. From this data it was possible to determine that portion of the total load carried by either the skin or the bulb-angles throughout the entire range of load.
