mm/min. 3.3 Creep test on GMT-sheet Initial deformation is instantaneous deformation, which is the summation of elastic and time-independent plastic deformation. Primary creep is called as transient creep, which exhibits relatively high speed of deformation, but reduced strain rate. Secondary creep is steady state creep, which maintains constant deformation through balance between hardening......
