is a non-degenerate bilinear form, that is, : is a map which is linear in both arguments, making it a bilinear form. By ϕ {\displaystyle \phi } being non-degenerate we mean that for each v ∈ V {\displaystyle v\in V} such that v ≠ 0 {\displaystyle v\neq 0} , there is a u ∈ V {\displaystyle u\in V} such that
where is the volume fraction of the fibers in the composite (and is the volume fraction of the matrix).. If it is assumed that the composite material behaves as a linear-elastic material, i.e., abiding Hooke's law = for some elastic modulus of the composite and some strain of the composite , then equations 1 and 2 can be combined to give
Vegard's law assumes that both components A and B in their pure form (i.e., before mixing) have the same crystal structure. Here, a A (1-x) B x is the lattice parameter of the solid solution, a A and a B are the lattice parameters of the pure constituents, and x is the molar fraction of B in the solid solution.
The simplest model of the dense fluid viscosity is a (truncated) power series of reduced mole density or pressure. Jossi et al. (1962) [14] presented such a model based on reduced mole density, but its most widespread form is the version proposed by Lohrenz et al. (1964) [15] which is displayed below.
The scalar triple product (also called the mixed product, box product, or triple scalar product) is defined as the dot product of one of the vectors with the cross product of the other two. Geometric interpretation
In tensor analysis, a mixed tensor is a tensor which is neither strictly covariant nor strictly contravariant; at least one of the indices of a mixed tensor will be a subscript (covariant) and at least one of the indices will be a superscript (contravariant).
Bond's theory and index brought a greater measure of openness to the calculations for selecting the type, size, and power ratings for ore milling equipment. [ 5 ] Bond was inducted with its first class into the National Mining Hall of Fame posthumously in 1988, [ 6 ] and received a Distinguished Achievement Medal by his alma mater, the Colorado ...
Multi-index notation is a mathematical notation that simplifies formulas used in multivariable calculus, partial differential equations and the theory of distributions, by generalising the concept of an integer index to an ordered tuple of indices.
