Predicting the Impact Puncture Response of Multilayer Flexible Food Packages Using Explicit Finite Element Models?

In previously presented work (ANTEC 2015 and FlexPackCon 2015), the authors developed a laboratory test method capable of ranking the impact puncture resistance (IPR) of multilayer flexible packages. This paper describes the development of nonlinear finite element models capable of predicting the IPR of the same multilayer structures. Information about the method used to obtain material properties at relevant strain rates, and comparisons between predicted and experimental responses are presented.
