Abstract

This paper presents the results of a simulation study of the drop weight test method and an evaluation of the theoretical results. Only through a thorough understanding of the limitations of each of the drop weight test procedures can the designer effectively use the data reported in the literature and understanding the limitations placed on the test results. As will be shown in this paper, this discrepancy is directly related to a lack of understanding of the test methodology and in some instances to the type of population distribution for the particular plastic population. The Bruceton and Probit drop weight impact test are importance tools for the design engineer to use in selecting a plastic for an impact application. However, when using both test methods, the sample standard deviations are necessary to accurately interpret the data. If an anomaly occurs in the Bruceton testing process, lack of convergence in the mean impact energy, it is recommended that the Bruceton method be discarded and the Probit Test conducted. If the plot of Failure Energy versus Percent failures is not a straight line, a complex phenomena with more than one variable in the population is occurring.
