[1.1] Materials & their applications Flashcards
What is compressive strength?
The ability to withstand being crushed or shortened by pushing forces
What is Tensile strength?
The ability to resist stretching or pulling forces
What is bending strength?
The ability to resist forces that may bend the material
What is shear strength?
The ability to resist sliding forces on a parallel plane
What is torsional strength?
The ability to withstand twisting forces from applied torque or torsion
What is Hardness?
The ability to resist abrasive wear such as scratching, surface indentation or cutting
What is toughness?
The ability to absorb impact force without fracture
What is plasticity?
The ability to be permanently deformed and retain the deformed shape
What is ductility?
The ability to be drawn out under tension, reducing the cross-sectional area without cracking, for example, stretching a material into a wire.
What is malleability?
The ability to withstand deformation by compression without cracking; malleability increase with a temperature rise.
What is elasticity?
The ability to be deformed and then return to the original shape when the force is removed.
What is density?
The mass of the material in a standard volume of space
What is fusibility?
The ability of the material to be fused or converted from a solid to a liquid or a molten state, usually by heat. Good fusibility is an essential property for a metal being cast.
What is magnetism?
The natural force between objects that causes the ,ate rial to attract iron or steels
What is corrosion resistance?
The ability of the material to withstand environmental attack or decay.
