failure

[′fāl·yər]
(engineering)
A permanent change in the volume of a powder or the stresses within it.
(mechanics)
Condition caused by collapse, break, or bending, so that a structure or structural element can no longer fulfill its purpose.

Failure

A condition when a structure or material ceases to fulfill its required purpose. The failure of a structural member may be caused by elastic deformation, fracture, or excessive deflection. The nonstructural failure of a material may be due to weathering, abrasion, or chemical action.

Failure

 

Failure is a consequence of a change in the parameters of a device or of its parts, resulting from internal physicochemical processes and the effect of the environment.

A distinction is made between sudden failure and gradual failure. Sudden failure is characterized by an abrupt change in the values of one or more fundamental parameters of a device (for example, the burnout of the incandescent filament in an electric lamp); in gradual failure, there is a slow change in the values of one or more fundamental parameters of a device (for example, the decrease of engine power to a level below the rated power). The criteria for failure are established in the technical specifications for a particular item.

As a result of failure, a device may stop operating completely, or its operating efficiency may fall below the permissible level. Failure of an element in a device that is not caused by damage to other elements is called independent failure; failure resulting from damage or the complete failure of other elements is called dependent failure.

What does it mean when you dream about a failure?

Dreaming about failing, in school or in some task, may simply be an expression of anxiety (i.e., it is not a sign predicting that someone will fail). People who regularly dream of failing are often perfectionists.

failure

In structural engineering, that condition of a structural element (or its material components) which renders it incapable of continuing the load-carrying function for which it was designed; may be caused by fracture or by excessive and permanent plastic deformation.

failure
