Bevel

(english) Angle formed between the prepared edge of the end of tube and a plane perpendicular to the surface. Standard pipe bevel is 30 degrees.

Normal strain:

(english) Strain measuring the intensity of deformation along an axis. Normal strain is usually denoted by . Average normal strain between two points is calculated as (Delta L / L), where L is the original distance between the points, and L is the change in that distance. Normal strain is often simply called strain.

Backwardation

(english) Market condition where the spot, or current price for a metal is higher than the three-month delivery price. This usually indicates immediate demand is perceived to be stronger than long-term demand. Not considered to be a "normal" market state (See Contango).

Acid Brittleness (Pickling Brittleness)

(english) Brittleness resulting from pickling steel in acid; hydrogen, formed by the interaction between iron and acid, is partially absorbed by the metal, causing acid brittleness.

Acid-Brittleness

(english) Brittleness resulting from pickling steel in acid; hydrogen, formed by the interaction between iron and acid, is partially absorbed by the metal, causing acid brittleness.

Usability

An informal measure of the ease with which a user interface can be learned and applied with efficiency and without errors

Adapters

Composting

(Environmental Engineering) The controlled aerobic degradation of organic wastes into a material which can be used for landscaping, landfill cover, or soil conditioning.

Brazing

(english) Joining metals by fusion of nonferrous alloys that have melting points above 800 F (425C), but lower than those of the metals being joined. May be accomplished by a torch. Filler metal is ordinarily in rod form in torch brazing; whereas in furnace and dip brazing the work material is first assembled and the filler metal may then be applied as wire, washers, clips, bands, or may be bonded, as in brazing sheet.

Defect removal efficiency (DRE)

(Software Engineering) a nondimension ratio (between 0 and 1) that provides an indication of the degree to which errors are removed from software before it is released to end-users

Use-case

(Software Engineering) a written description that defines a very specific interaction between a user and a system, often (but not always) written in the form of a usage scenario

Sulfate Attack

(Concrete Engineering) Deleterious chemical and/or physical re-action between sulfates in ground water or soil and certain constituents in cement, which result in expansion and disruption of the concrete.
