(english) The point beyond which the deformations of a structure or material are no longer purely elastic.
(english) Bending deformation, i.e., deformation by increasing curvature.
(english) A force-displacement relationship which is both linear and elastic. For a structure, this means the deformation is proportional to the loading, and deformations disappear on unloading. For a material, the concept is the same except strain substitutes for deformation, and stress substitutes for load.
(english) Not surprisingly, the opposite of elastic. A deformation of a structure or material under load is described as inelastic when the deformation remains after the load is removed. The term plastic is often used with the same meaning.
(english) The tendency of a metal or material to fracture without undergoing appreciable plastic deformation.
(english) Upper limit of normal stress of a beam at which fracture or excessive plastic deformation occurs.
(english) The intensity of deformation at a point in an object. See normal strain and shear strain.
(english) Fracture preceded by little or negligible plastic deformation.

(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.
(english) Fracture with little or no plastic deformation.
