Dear ANSYS Experts, I have been asked to do some primary (transient) creep modeling using ANSYS. The creep model is Bailey-Norton model (strain = C0*stress^C1*time^C2*exp(-C4/Temp)) please note that this equation obtains the strain - reference: Table 1 of Mukhrejee et al., (2016), “Creep Constitutive Models Suitable for Solder Alloys in Electronic Assemblies”, Journal of Electronic Packaging, Vol 138, 3. When I read TFM, I noticed that this model is given for the strain rate (strain rate = C0*stress^C1*time^C2*exp(-C4/Temp)), in Mechanical APDL Material Reference R19.0. This has been scratching my mind in the last few days. Is it just a typo somewhere or am I missing something? I would love some inputs from ANSYS guys of this list.
