List of Materials Properties
A material's property (or material property) is an intensive property of some material, i.e. a physical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
A property may be a constant or may be a function of one or more independent variables, such as temperature. Materials properties often vary to some degree according to the direction in the material in which they are measured, a condition referred to as anisotropy. Materials properties that relate to different physical phenomena often behave linearly (or approximately so) in a given operating range. Modeling them as linear can significantly simplify the differential constitutive equations that the property describes.
Some materials are used in relevant equations to predict the attributes of a system a priori.
The properties are measured by standardized test methods. Many such methods have been documented by their respective user communities and published through the Internet; see ASTM International.
Hindrance is property in metal of magnetic
- Brittleness: Ability of a material to break or shatter without significant deformation when under stress; opposite of plasticity,examples:glass,concrete,cast iron, ceramics etc.
- Bulk modulus: Ratio of pressure to volumetric compression (GPa) or ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume.
- Coefficient of restitution:the ratio of the final to initial relative velocity between two objects after they collide. Range : 0-1, 1 for perfectly elastic collision.
- Compressive strength: Maximum stress a material can withstand before compressive failure (MPa)
- Creep: The slow and gradual deformation of an object with respect to time
- Ductility: Ability of a material to deform under tensile load (% elongation)
- Durability: Ability to withstand wear, pressure, or damage; hard-wearing.
- Elasticity: Ability of a body to resist a distorting influence or stress and to return to its original size and shape when the stress is removed
- Fatigue limit: Maximum stress a material can withstand under repeated loading (MPa)
- Flexibility: Ability of an object to bend or deform in response to an applied force; pliability; complementary to stiffness
- Flexural modulus
- Flexural strength : The stresses in a material just before it yields.
- Fracture toughness: Ability of a material containing a crack to resist fracture (J/m^2)
- Friction coefficient: The amount of force normal to surface which converts to force resisting relative movement of contacting surfaces between material pair
- Hardness: Ability to withstand surface indentation and scratching (e.g. Brinell hardness number)
- Malleability: Ability of the material to be flattened into thin sheets under applications of heavy compressive forces without cracking by hot or cold working means.
- Mass diffusivity: Ability of one substance to diffuse through another
- Plasticity: Ability of a material to undergo irreversible or permanent deformations without breaking or rupturing; opposite of brittleness
- Poisson's ratio: Ratio of lateral strain to axial strain (no units)
- Resilience: Ability of a material to absorb energy when it is deformed elastically (MPa); combination of strength and elasticity
- Shear modulus: Ratio of shear stress to shear strain (MPa)
- Shear strength: Maximum shear stress a material can withstand
- Slip: A tendency of a material's particles to undergo plastic deformation due to a dislocation motion within the material. Common in Crystals.
- Specific modulus: Modulus per unit volume (MPa/m^3)
- Specific strength: Strength per unit density (Nm/kg)
- Specific weight: Weight per unit volume (N/m^3)
- Stiffness: Ability of an object to resist deformation in response to an applied force; rigidity; complementary to flexibility
- Surface roughness:the deviations in the direction of the normal vector of a real surface from its ideal form.
- Tensile strength: Maximum tensile stress of a material can withstand before failure (MPa)
- Toughness: Ability of a material to absorb energy (or withstand shock) and plastically deform without fracturing (or rupturing); a material's resistance to fracture when stressed; combination of strength and plasticity
- Viscosity: A fluid's resistance to gradual deformation by tensile or shear stress; thickness
- Yield strength: The stress at which a material starts to yield plastically (MPa)
- Young's modulus: Ratio of linear stress to linear strain (MPa)
- Strength of materials (relation of various strengths) etc.
