Strength (material property)
Strength (material property)
Ability to resist forces without breaking or failing
Five main types of strength
Five main types of strength
Tensile, compressive, shear, bending, torsional
Tensile strength
Tensile strength
Resistance to being pulled apart
Compressive strength
Compressive strength
Resistance to being squashed or compressed
Shear strength
Shear strength
Resistance to sliding forces acting parallel to surface
Bending strength
Bending strength
Resistance to forces that try to bend material
Torsional strength
Torsional strength
Resistance to twisting forces
Hardness
Hardness
Resistance to surface damage (scratching, indentation, wear)
Ductility
Ductility
Can be stretched & drawn into thinner sections without breaking
Malleability
Malleability
Can be hammered, rolled, or pressed into shapes without cracking
Toughness
Toughness
Ability to absorb energy from impacts without fracturing
Brittleness
Brittleness
Fractures easily under impact with little or no warning
Elasticity
Elasticity
Returns to original shape after deforming force is removed
Elastic limit
Elastic limit
Beyond this, material becomes permanently deformed
Conductivity
Conductivity
How easily heat, electricity, or sound flows through material
