Impact Loading Experimentation

This is a brief report of an impact loading test method. It evolved from experimentation leading to develop a test method which lends itself to analytical analysis and, as a consequence, to better understanding of characteristics related to impact loading and to resistance of structural material and/or structural systems to such loading. Refinements in data collection and possibly in loading technique are needed for fully proving the validity of the intended analysis. It was found that: 1) consecutive impact loading with a sandbag using 6-inch increment in drop height caused failure of the panel prior to that of the single drop loading; 2) panel evaluation for impact strength cannot be done based on sandbag loading alone unless the results can be related to other types of impact loading which develop in use; and 3) the 60-1b. sandbag drops appeared to be two or more times as damaging as the man-jump (150 lb.).
