Fracture Toughness
Fracture toughness is a material's ability to resist the growth of cracks when stressed. It measures how much force a material can withstand before a crack starts to spread. In practical terms, a tough material can absorb energy and deform without breaking, which is crucial in safety-critical applications like bridges, airplanes, and bones. Engineers evaluate fracture toughness to ensure materials can endure stress and avoid sudden failure, making it a key factor in design and material selection for durability and reliability.

Fracture toughness is a material's ability to resist crack propagation when stress is applied. It measures how much stress a material can withstand before a crack begins to grow, which is crucial in engineering and construction. Higher fracture toughness means a material is less likely to fail unexpectedly under pressure. This property is particularly important for materials used in critical applications, like airplane wings or bridges, where safety is paramount. Understanding fracture toughness helps engineers choose the right materials to ensure structures can handle forces without breaking.
