What is Dynamic Fracture Toughness via Hopkinson Bar about?

The paper introduces a method for determining dynamic fracture toughness using a notched three-point bend specimen under dynamic loading, accounting for inertia effects. The authors utilize a modified Hopkinson pressure bar to measure applied force and load-point displacement, demonstrating good agreement with traditional strain measurement techniques. The method is particularly effective for high-temperature testing of brittle materials and provides insights into the relationship between stress-intensity f
