Testing Impact Load Cell Calculations of Material Fracture

nbsp 0183 32 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...
