New creep law

Publisher: Maney Publishing
In the present paper, a new creep law describing the high temperature strain rate of materials, which is applicable to both high and low values of stresses, is proposed. In a similar way to the known hyperbolic sine law, the proposed equation guarantees a potential behaviour for low stress values (in accordance to the power law of creep) and a pure exponential behaviour for high stress values, according to the power breakdown law of creep. The differences and possible advantages of the proposed equation are analysed in comparison with the hyperbolic sine law.
