Strain hardening exponent — The strain hardening exponent (also called strain hardening index), noted as n , is a materials constant which is used in calculations for stress strain behaviour in work hardening. In the formula σ = K ε n, σ represents the applied stress on the … Wikipedia
Stress–strain curve — During testing of a material sample, the stress–strain curve is a graphical representation of the relationship between stress, derived from measuring the load applied on the sample, and strain, derived from measuring the deformation of the sample … Wikipedia
Work hardening — Work hardening, also known as strain hardening or cold working, is the strengthening of a metal by plastic deformation. This strengthening occurs because of dislocation movements within the crystal structure of the material.[1] Any material with… … Wikipedia
Dynamic strain aging — Although sometimes dynamic strain aging is used interchangeably with the Portevin–Le Chatelier effect (or serrated yielding), dynamic strain aging refers specifically to the microscopic mechanism that induces the Portevin–Le Chatelier effect.… … Wikipedia
Viscoplasticity — Figure 1. Elements used in one dimensional models of viscoplastic materials. Viscoplasticity is a theory in continuum mechanics that describes the rate dependent inelastic behavior of solids. Rate dependence in this context means that the… … Wikipedia
Tensile strength — sigma {UTS}, or S U is the stress at which a material breaks or permanently deforms. Tensile strength is an intensive property and, consequently, does not depend on the size of the test specimen. However, it is dependent on the preparation of the … Wikipedia
T-criterion — The T failure criterion [Andrianopoulos, N.P., Atkins, A.G., Experimental Determination of the Failure Parameters ΤD,0 and ΤV,0 in Mild Steels According to the T criterion, ECF9 Reliability and Structural Integrity of Advanced Materials, Vol. III … Wikipedia
Plasticity (physics) — Plastic material redirects here. For the material used in manufacturing, see Plastic. Continuum mechanics … Wikipedia
Yield (engineering) — The yield strength or yield point of a material is defined in engineering and materials science as the stress at which a material begins to deform plastically. Prior to the yield point the material will deform elastically and will return to its… … Wikipedia
Ramberg-Osgood relationship — The Ramberg Osgood equation was created to describe the non linear relationship between stress and strain mdash;that is, the stress strain curve mdash;in materials near their yield points. It is especially useful for metals that harden with… … Wikipedia
Structural engineering — is a field of engineering dealing with the analysis and design of structures that support or resist loads. Structural engineering is usually considered a speciality within civil engineering, but it can also be studied in its own right. [cite… … Wikipedia
