Aluminium alloys (or aluminum alloys; see spelling differences) are alloys in which aluminium (Al) is the predominant metal.
# A material is brittle if, when subjected to stress, it breaks without significant plastic deformation.
In science, buckling is a mathematical instability that leads to a failure mode.
The, also known as the Charpy V-notch test, is a standardized high strain-rate test which determines the amount of energy absorbed by a material during fracture.
In mechanics, compression is the application of balanced inward ("pushing") forces to different points on a material or structure, that is, forces with no net sum or torque directed so as to reduce its size in one or more directions.
Compression members are structural elements that are pushed together or carry a load, more technically they are subjected only to axial compressive forces.
Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate.
In long, slender structural elements — such as columns or truss bars — an increase of compressive force F leads to structural failure due to buckling at lower stress than the compressive strength.
In materials science, creep (sometimes called cold flow) is the tendency of a solid material to move slowly or deform permanently under the influence of mechanical stresses.
In engineering, deflection is the degree to which a structural element is displaced under a load.
In materials science, deformation refers to any changes in the shape or size of an object due to-.
Deformation in continuum mechanics is the transformation of a body from a reference configuration to a current configuration.
A deformation mechanism map is a way of representing the dominant deformation mechanism in a material loaded under a given set of conditions and thereby its likely failure mode.
Dynamics is the branch of applied mathematics (specifically classical mechanics) concerned with the study of forces and torques and their effect on motion, as opposed to kinematics, which studies the motion of objects without reference to these forces.
In physics, elasticity (from Greek ἐλαστός "ductible") is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed.
Factors of safety (FoS), is also known as (and used interchangeably with) safety factor (SF), is a term describing the load carrying capacity of a system beyond the expected or actual loads.
In materials science, fatigue is the weakening of a material caused by repeatedly applied loads.
Forensic engineering has been defined as "the investigation of failures - ranging from serviceability to catastrophic - which may lead to legal activity, including both civil and criminal". It therefore includes the investigation of materials, products, structures or components that fail or do not operate or function as intended, causing personal injury, damage to property or economic loss.
Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials.
In materials science, fracture toughness is a property which describes the ability of a material to resist fracture, and is one of the most important properties of any material for many design applications.
Grain-boundary strengthening (or Hall–Petch strengthening) is a method of strengthening materials by changing their average crystallite (grain) size.
Izod impact testing is an ASTM standard method of determining the impact resistance of materials.
James Edward Gordon (UK, 1913–1998) was one of the founders of materials science and biomechanics, and a well-known author of three books on structures and materials, which have been translated in many languages and are still widely used in schools and universities.
Material selection is a step in the process of designing any physical object.
Michael Farries Ashby CBE, FRS, FREng (born 20 November 1935) is a British metallurgical engineer.
Microstructure is the very small scale structure of a material, defined as the structure of a prepared surface of material as revealed by a microscope above 25× magnification.
Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero.
The newton (symbol: N) is the International System of Units (SI) derived unit of force.
The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength.
In physics and materials science, plasticity describes the deformation of a (solid) material undergoing non-reversible changes of shape in response to applied forces.
Poisson's ratio, denoted by the Greek letter 'nu', \nu, and named after Siméon Poisson, is the negative of the ratio of (signed) transverse strain to (signed) axial strain.
The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units.
Precipitation hardening, also called age hardening or particle hardening, is a heat treatment technique used to increase the yield strength of malleable materials, including most structural alloys of aluminium, magnesium, nickel, titanium, and some steels and stainless steels.
Scissors are hand-operated shearing tools.
In engineering, shear strength is the strength of a material or component against the type of yield or structural failure where the material or component fails in shear.
A shear stress, often denoted by (Greek: tau), is the component of stress coplanar with a material cross section.
Solid solution strengthening is a type of alloying that can be used to improve the strength of a pure metal.
The specific strength is a material's strength (force per unit area at failure) divided by its density.
Statics is the branch of mechanics that is concerned with the analysis of loads (force and torque, or "moment") acting on physical systems that do not experience an acceleration (a.
Stepan Prokopovych Timoshenko (Степан Прокопович Тимошенко, a) (December 23, 1878 – May 29, 1972), was a Russian (modern territory of Ukraine) and, later, an American.
Methods have been devised to modify the yield strength, ductility, and toughness of both crystalline and amorphous materials.
In continuum mechanics, stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other, while strain is the measure of the deformation of the material.
A stress concentration (often called stress raisers or stress risers) is a location in an object where stress is concentrated.
The relationship between the stress and strain that a particular material displays is known as that particular material's stress–strain curve.
In mathematics, tensors are geometric objects that describe linear relations between geometric vectors, scalars, and other tensors.
In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing.
Ultimate tensile strength (UTS), often shortened to tensile strength (TS), ultimate strength, or Ftu within equations, is the capacity of a material or structure to withstand loads tending to elongate, as opposed to compressive strength, which withstands loads tending to reduce size.
A universal testing machine (UTM), also known as a universal tester, materials testing machine or materials test frame, is used to test the tensile strength and compressive strength of materials.
The von Mises yield criterion (also known as the maximum distortion energy criterion) suggests that yielding of a ductile material begins when the second deviatoric stress invariant J_2 reaches a critical value.
Work hardening, also known as strain hardening, is the strengthening of a metal or polymer by plastic deformation.
The yield point is the point on a stress–strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior.
