Final answer:
Metals are less affected by brittle fracture compared to ceramics like glass and concrete.
Step-by-step explanation:
Brittle fracture is a type of fracture where the material breaks without significant plastic deformation.
In other words, it breaks easily when subjected to stress. However, some materials are less affected by brittle fracture than others. For example, metals such as steel are more ductile and less prone to brittle fracture compared to ceramics like glass and concrete.
Metals have the ability to undergo plastic deformation before fracturing, which gives them more resistance to brittle fracture.
