working properties of materials Flashcards
elasticity
other properties
the ability to be deformed and then return to the original shape when the force is removed
plasicity
other properties
the ability to be permanently deformed (shaped) and retain the deformed shape
malleability
other properties
the ability to withstand deformation by compression without cracking. malleability increases with the rise of temperature
ductility
other properties
the ability to be drawn out under tension, reducing the cross-section area without cracking
hardness
other properties
the ability to resist abrasive wear such as scratching, surface indentation or cutting
toughness
other properties
the ability to absorb impact force without fracture
durability
other properties
the ability to withstand general wear over a period of time
biodegradability
other properties
the ability to naturally decompose by the actions of bacteria or other living organisms
bending strength
strength
the ability to resist forces that may bend the material
compressive strength
strength
ability to withstand being crushed or shortened by pushing forces
tensile strength
strength
the ability to resist stretching or pulling forces
shear strength
strength
the ability to resist sliding forces on a parallel plane
torsional strength
strength
the ability to withstand twisting forces from applied torque or torsion
electrical conductor
conductivity
allows the flow of electrical current through the material. a good conductor gives very little resistance to the flow of charge
electrical insulator
conductivity
does not allow the flow of electricity through the material
