WebJul 27, 2024 · Brittle cracking resistance is one of the most important material features. The fracture toughness in mode I (K IC) is the parameter considered to be a material constant, which determined the material’s resistance to brittle cracking.It is independent of the thickness of the material being tested because it refers to a constant state of stress. http://erepository.uonbi.ac.ke/bitstream/handle/11295/93555/Njenga_The%20binder%20effect%20of%20povidone%20on%20the%20mechanical%20properties%20of%20paracetamol%20containing%20tablets.pdf?sequence=6
