What is toughness materials?

Toughness in materials refers to their ability to absorb energy and deform plastically without fracturing. It is a critical property that indicates how well a material can withstand stress and impact, making it especially important in applications where durability and resistance to failure are essential. Tough materials can endure significant amounts of strain and are often characterized by a combination of strength and ductility. Common examples include metals like steel, which are used in construction and manufacturing due to their toughness.
