Ductile Fracture

Ductile fracture is a type of material failure that occurs when a material deforms significantly under stress before breaking. It involves extensive plastic deformation, where the material stretches or thins out, forming tiny cavities or voids inside. These voids grow and connect, leading to a final fracture that is usually accompanied by visible deformation. This behavior is common in metals like aluminum and steel, allowing them to absorb impact energy and deform without immediate breaking, making them generally tough and reliable in engineering applications.
