    Abstract

    A dynamic gage, capable of continuously measuring high-rate displacements of structures, has been developed and tested by the research team of the Protective Technologies Research & Development Center (PTR&DC) of the Faculty of Engineering Sciences of the Ben-Gurion University of the Negev. The gage, which was originally developed in order to monitor the time-dependent displacements of concrete slabs subjected to explosion-generated blast wave impacts, can be used to monitor the displacement of any structure that is exposed to high-rate dynamic loads. The displacement gage is based on a torsion tube, twisted by a long flexure element that is connected to the measured point or structure. The twist of the torsion tube is monitored by strain gages. The displacement gage was tested in the impact pendulum laboratory of the PTR&DC, and will be used in high explosive (HE) field tests.
