Abstract:

The Armys helmet blunt impact test method is complex due to the realities of testing a helmet system. To better understand the complexities of the test method, this effort briefly investigates the roles of multiple variables temperature dependencies of materials being evaluated, foam pad relaxation post impact, trends and repeatability of the test system. Rapid prototyping was used to create tools that could remove degrees of freedom in the test set up, potentially reducing operator dependencies.
