What is a structural material called if it can absorb substantial energy prior to failure________________?
Show answer Hide answer
Answer: B. toughness
Explanation
Toughness is the mechanical property enabling materials to absorb energy before fracturing. Tough materials undergo significant plastic deformation under high stress without sudden failure. The area under the entire stress strain curve represents the material toughness value. Structural materials must resist both high static loads and sudden impact forces safely. Toughness combines both strength and ductility properties in engineering material selection. Standard impact tests like Charpy V-notch measure the toughness of metallic alloys.
Engineers select tough steels for bridges and pressure vessels to prevent catastrophic brittle failure. Automotive chassis components require high toughness to absorb energy during crash impacts. Material science testing ensures structural components meet strict safety standards worldwide. Ductility refers specifically to a material ability to deform plastically in tension. Resilience measures the capacity to absorb energy elastically without permanent deformation. Shock proof is an informal term rather than a standard mechanical material property.
