(english) Stability is best defined as the opposite of instability, which is the occurrence of large structural deformations which are not the result of material failure.
(english) Any vector can be expressed as a collection of vectors whose sum is equal to the original vector. Each vector in this collection is a component of the original vector. It is common to express a vector in terms of components which are parallel to the x and y axes.
(Concrete Engineering) The deposit of a gray scum or gray dust on the inside surface of a subgrade wall or floor; as the result of moisture moving through the concrete and washing certain chemicals from the concrete mass.
(english) The displacement and / or detachment of metallic particles from a surface as a consequence of being exposed to flowing fluids or gases.
(Environmental Engineering) Chlorofluorocarbons, chemicals which result in a depletion of the ozone layer in the upper atmosphere.
(Concrete Engineering) A metal mold in the form of a truncated cone with a top diameter of 4”, a bottom diameter of 8”, and a height of 12”, used to fabricate the specimen for a slump test.
(Software Engineering) the creation of a mock-up of an application
(english) A change in position. A displacement may be a translation a rotation or a combination of those.
(Software Engineering) a modeling notation that represents a functional decomposition of a system
(english) The process of annealing in a protective atmosphere so as to prevent discoloration of the bright surface desired.
(english) The proportional constant between stress and strain for material with linear elastic behavior: calculated as stress divided by strain. Modulus of elasticity can be interpreted as the slope of the stress-strain graph. It is usually denoted as E, sometimes known as Young's Modulus Y, or E-Modulus.
(Concrete Engineering) A quantity of cement contained in a unit volume of concrete or mortar, ordinarily expressed as pounds, barrels, or bags per cubic yard.
