MSC.MARC Creep/Stress Relaxation Model
This model is used to describe the creep behavior of a material, based on experimental creep data. This TestPak includes creep data taken for 1000 hours. The creep data can be specified to fit a power law model, or as a piecewise linear curve, as a table of creep strain vs. time.
: 6 tensile bars[details]
This block of data defines the parameters and material properties used in a creep analysis. This analysis is necessary when the part will be subjected to constant loads, where creeping of the material must be taken into account.
