Testing Impact Load Cell Calculations of Material Fracture Toughness and Strength Using 3D-Printed Sandstone

Short impact load cell (SILC) tests provide insight on the dynamic breakage behaviour of rocks. The measured impact force to first fracture of a rock specimen is used to calculate properties such as fracture toughness, tensile strength, and stiffness. To explore the repeatability and performance of the SILC test and verify the underlying assumptions for interpreting the test measurements, a comprehensive SILC testing program was conducted using...
