DSIAC was asked if there are any equations that correlate impact energy to the resulting damage diameter in a composite material. A DSIAC subject matter expert at Texas Research Institute Austin (TRI Austin) discussed the issue with the inquirer and found a number of references that provide experimentally-based correlations between impact energy and damage diameter, although these are very specific to the materials system examined. An expression was identified to determine damage diameter; however, this required knowing the impact force rather than the impact energy, which required using additional instrumentation. A report summarizing the findings was delivered to the inquirer.
