Fracture toughness is a material\u2019s ability to resist the propagation of cracks. It quantifies how well a material can withstand stress in the presence of a flaw or defect, and it is especially important in brittle materials. Fracture toughness is typically denoted as K\u2081c and measured in MPa\u00b7\u221am. A higher K\u2081c value means the material can better resist catastrophic failure even when microscopic cracks exist. Why is Fracture Toughness Important? In real-world engineering, no material is flawless\u2014microcracks, voids, or inclusions often exist due to machining, fatigue, or material limitations. If a material has low fracture toughness, these small flaws can grow under stress, quickly leading to
