Measuring strain in sheet metals

Abstract

A sensitive and precise experimental system able to time-track the static and dynamic response of steel sheets to intense loads is hereby described. This methodological article is based on a specific investigation carried out in order to verify the correct functioning and safety conditions of a large sheet metal structure. Several suggestions and practical tricks are presented in ample details describing in what ways they allow to improve the results of the experiment.
