Abstract : This report discusses the various types of foamed thermoplastic materials used as cushioning systems in military containers and their more important properties. The primary aspects of cushioning design theory currently being used by container designers to predict the response of packaged items when subjected to free-fall drop tests is discussed. The test results of all available military container designs utilizing foamed plastic cushioning systems are analyzed to determine the statistical significance of the various factors affecting container response. The analysis of the factors involved are then compared with the cushioning theory and the results are discussed. The Superimposed Dynamic Cushioning Curve technique is then presented as an improved method for presenting the cushioning properties of foamed plastic materials. (Author-PL)
