Description
Summary:— Tempered glass is a transparent material that can withstand various shocks and constant loads, which is widely used in the field of safety protection. This manuscript presents the determination of Johnson–Holmquist (JH-2) model parameters for tempered glass and investigates the effect of strain rate on its strength through quasi-static and dynamic compression tests. The hydrostatic tensile pressure was indirectly determined via split tensile tests, and literature data were employed to calculate the value of HEL and EOS. The JH-2 model accurately predicted the real shapes of strain waves in the input and output bar of SHPB tests and was capable of describing the mechanical behavior of the brittle material from elasticity to fracture. The determined parameters for tempered glass were validated to represent the response to shock and impact loads.
