Mechanical Properties Flashcards
Mechanical properties
Associated with how a material reacts to an external force
Compressive strength
The ability to withstand being crushed or shortened by pushing forces
Tensile strength
The ability to resist stretching or pulling forces
Bending strength
The ability to resist forces that may bend the material
Shear strength
The ability to resist sliding forces on a parallel plane
Torsional strength
The ability to withstand twisting forces from applied torque or tension
Hardness
The ability to resist abrasive wear such scratching, surface indentation and cutting
Toughness
The ability to absorb impact force without fracture
Plasticity
The ability to be permanently deformed and retain the shape to which the material has been deformed
Ductility
The ability to be drawn out under tension, reducing the cross-sectional area without cracking, for example stretching a material into a wire
Malleability
The ability to withstand deformation by compression without cracking
Increases with a rise in temperature
Elasticity
The ability to be deformed and then return to the original shape when the force is removed
Examples of mechanical properties
Compressive strength Tensile strength Bending strength Shear strength Torsional strength Hardness Toughness Plasticity Ductility Malleability Elasticity
