Experimental Validation of the Butyl-Rubber Finite Element (FE) Material Model for the Blast-Mitigating Floor Mat

reportActive / Technical Report | Accession Number: ADA620802 | Open PDF

Abstract:

This report was written by the author under the Engineer Scientist Exchange Program activity in the US Army Research Laboratory from April 2013 to September 2014. To clarify the accuracy of finite element FE material models for butyl rubber, the component-level loading test was conducted on drop testers in various loading conditions. The test results are compared with the Finite Element Analysis FEA results of each FE-material model, and the errors in each material model are discussed on various metrics.
