81Normal mode — For other types of mode, see Mode (disambiguation). Vibration of a single normal mode of a circular disc with a pinned boundary condition along the entire outer edge. See other modes. A normal mode of an oscillating system is a pattern of motio …
82Superalloy — A superalloy, or high performance alloy, is an alloy that exhibits excellent mechanical strength and creep resistance at high temperatures, good surface stability, and corrosion and oxidation resistance. Superalloys typically have an austenitic… …

84Yield (engineering) — The yield strength or yield point of a material is defined in engineering and materials science as the stress at which a material begins to deform plastically. Prior to the yield point the material will deform elastically and will return to its… …
85Micromechanics — (or, more precisely, micromechanics of materials) is the analysis of composite or heterogeneous materials on the level of the individual constituents that constitute these materials. Contents 1 Aims of micromechanics of materials 2 Analytical… …
86List of algebraic structures — In universal algebra, a branch of pure mathematics, an algebraic structure is a variety or quasivariety. Abstract algebra is primarily the study of algebraic structures and their properties. Some axiomatic formal systems that are neither… …
87Numerical continuation — is a method of computing approximate solutions of a system of parameterized nonlinear equations, The parameter λ is usually a real scalar, and the solution an n vector. For a fixed parameter value λ,, maps Euclidean n space into itself. Often the …
88Arne Bjerhammar — (born 1917) is a Swedish geodesist. He is doctor at Kungliga Tekniska Högskolan (KTH) in Stockholm. He was born in Båstad, Scania in the south of Sweden. He has among other things developed a matrix algebra with generalised inverses, a method… …
89Numerical range — In the mathematical field of linear algebra and convex analysis, the numerical range of a square matrix with complex entries is a subset of the complex plane associated to the matrix. If A is an n × n matrix with complex entries, then… …
90Kernel smoother — A kernel smoother is a statistical technique for estimating a real valued function f(X),,left( Xin mathbb{R}^{p} ight) by using its noisy observations, when no parametric model for this function is known. The estimated function is smooth, and the …
