strain coefficient
81Mu — can be:*Mu (letter), Μ or μ, a letter in the Greek alphabet.μ is used as a symbol for: **The SI prefix micro , denoting a factor of 10−6 (one millionth). ***μ by itself is often used as the unit of strain, though in this context it retains its SI …
82Reinforced concrete — is concrete in which reinforcement bars ( rebars ), reinforcement grids, plates or fibers have been incorporated to strengthen the concrete in tension. It was invented by French gardener Joseph Monier in 1849 and patented in 1867.[1] The term… …
83Dynamic mechanical spectroscopy — In the technique of Dynamic Mechanical Spectroscopy a material (usually a slab of polymer) is exposed to a periodical deformation. The deformation can be in tensile, compression or bending mode but torsional deformations are the most practical… …
84Pyroelectricity — is the ability of certain materials to generate an electrical potential when they are heated or cooled. As a result of this change in temperature, positive and negative charges move to opposite ends through migration (i.e., the material becomes… …
85Internal energy — In thermodynamics, the internal energy of a thermodynamic system, or a body with well defined boundaries, denoted by U , or sometimes E , is the total of the kinetic energy due to the motion of molecules (translational, rotational, vibrational)… …
86Refractory metals — are a class of metals that are extraordinarily resistant to heat and wear. Refractory metals are said to be poorly resistant to oxidation and corrosion. [UFL EMA 6625: Advanced Metal Processing, Summer 2008, Lecture 09] These properties make them …
87Similitude (model) — For other uses, see Similitude (disambiguation). A full scale X 43 Wind tunnel test. The test is designed to have dynamic similitude with the real application to ensure valid results. Similitude is a concept applicable to the testing of… …
88Electrostriction — is a property of all electrical non conductors, or dielectrics, that causes them to change their shape under the application of an electric field. (Compare with magnetostriction.) Explanation Electrostriction is a property of all dielectric… …
89Overhead power line — This article is about power lines for general transmission of electrical power. For overhead lines used to power road and rail vehicles, see Overhead lines. Transmission lines in Lund, Sweden …
90Invariants of tensors — In mathematics, in the fields of multilinear algebra and representation theory, invariants of tensors are coefficients of the characteristic polynomial of the tensor A :: det (mathbf{A} lambda mathbf{E}) = 0 The first invariant of an n times; n… …
