High-speed measurements and simulations of blast loaded plates

Boekbijdrage - Boekhoofdstuk Conferentiebijdrage

Measuring the dynamic response of structures due to blast loading is rather complex because of the high strain rates, the transient nature of the deformation and the interactions between the explosion and the structure. The blast response of structures has been an area of active research in recent years. Several studies have investigated dynamic deformations due to explosive blast loading on plates using strain gauges, accelerometers, velocity meters or pressure sensors. The disadvantage of these measurement devices is that they only provide point-wise information.
In this paper three aluminum plates are subjected to a free air explosive loading with 40g of C4. Combining two high-speed cameras in a stereoscopic and the digital image correlation technique, the full-field deformation is identified. Furthermore, the identified deformation fields are compared by data computed with an explicit finite element method. The Johnson-Cook material model is used to simulate the plastic behavior of the aluminum plate. A good agreement has been found between both experimental and numerical data.
