This paper presents results from experiments on soft impact testing of glass plates. In the experiments, a 50-kg twin-tire pendulum was used to strike different glass plates at speeds of up to 4.85 m/s. The impact parameters that were defined and measured include the micro-strain in the glass plates, pendulum acceleration, duration of contact, pendulum height, and maximum tire track values. A total of 240 impacts on 17 specimens were carried out for different glass thicknesses (5, 6, 8, and 10 mm) and boundary conditions (four sides, two sides and four pin points supported). Tempered monolithic and toughened bi-layered laminated plates were tested. To find out if the selected parameters represent the phenomena, multiple regression analysis was carried out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
