Abstract
The paper presents a new methodology for determination of the same time to rupture surfaces on the basis of creep tests carried out on pure copper under plane stress state at elevated temperature (523K). It is proposed to adopt this methodology in order to determine the surfaces of the same time to obtain minimum creep rate and surfaces of the same time to tertiary creep period. Analysis of all types of the isochronous surfaces proved that the damage evolution in copper develops proportionally until the creep rupture is achieved.
