The Thematic Group held teleconference meetings on 6 February and 19 of March. The Group decided to use teleconference-format in order to draft and edit a review of the methods concerning far-field blast resistance against glass-made structural element. The review deals in detail with three testing methodologies in comparative perspective: shock tubes, high explosives, and numerical methods. The review will be finalized in a third teleconference taking place in May. The next face-to-face meeting will be held in late-June at the JRC, Ispra.
