Mechanical behavior of aluminum foils as micro structural material under low velocity impact loading

摘要

If many works consist in describing the static behavior of micro materials, not one concerns impact loading. Therefore, the proposed work aims to analyze the dynamic behavior of micro material items under low velocity impact loading, with an application for aluminum foils as micro structural material. The purpose of this experimental study is also to establish the feasibility and the performance of an impact testing machine for micro materials. In comparison of quasi-static reference curves, the structural responses of dynamically loading micro plates underline the specificity and so the necessity of impact tests. The material strength repartition exhibiting a few scattering data allows to validate the drop-weight set-up, confirms the differences statistically and authorizes some future investigation.
