Unified stress-rupture equation

A unified stress-rupture equation and a unified equation are given in this paper. The equation can compound the L-M equation, G-D equation, M-S equation and M-H equation into a unified form, furthermore, it can express the relation among the stress-rupture limit, stress and temperature exactly which cannot be expressed by those four equations. Contrasted with those four stress-rupture equations given in the standard, this unified equation has the advantages of high precision and wide applicability.
