Mohr–Coulomb theory is a mathematical model (see yield surface) describing the response of brittle materials such as concrete, or rubble piles, to shear stress as well as normal stress. Most of the classical engineering materials follow this rule in at least a portion of their shear failure envelope.
Equations (3) and (4) are the simplest formulae satisfying three requirements: 1) Asymptotically for both short and long times , ˙ (, ′), should be a power function of time; and 2) so should the aging rate, given by () /) (power functions are indicated by self-similarity conditions); and 3) (, ′) / ′ > (this condition is required to ...
Material strength refers to the point on the engineering stress–strain curve (yield stress) beyond which the material experiences deformations that will not be completely reversed upon removal of the loading and as a result, the member will have a permanent deflection. The ultimate strength of the material refers to the maximum value of ...
The first constitutive equation (constitutive law) was developed by Robert Hooke and is known as Hooke's law.It deals with the case of linear elastic materials.Following this discovery, this type of equation, often called a "stress-strain relation" in this example, but also called a "constitutive assumption" or an "equation of state" was commonly used.
Marcus's method is a structural analysis used in the design of reinforced concrete slabs.The method was developed by Henri Marcus and described in 1938 in Die Theorie elastischer Gewebe und ihre Anwendung auf die Berechnung biegsamer Platten. [1]

From January 2008 to December 2012, if you bought shares in companies when Joshua I. Smith joined the board, and sold them when he left, you would have a 7.6 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
