Abstract

This paper deals with full-field measurements of aluminum plates under free air blast loading conditions. A stereoscopic high-speed camera system is used to capture the plate response with an inter frame rate of 6,000 fps. The transient deformation fields are calculated using a three-dimensional digital image correlation technique. The deformation fields are compared by data computed with an explicit finite element method. A good agreement has been found between both experimental and numerical data. Furthermore, a mixed experimental-numerical method is proposed to determine the elasto-plastic material parameters during a free air blast event. This method is solely validated using a virtual experiment.
