3.1.1 Constitutive Equations
In consideration of the geometry constraint effect that non-standard
specimen has, it is necessary to correctly carry out the correlation
evaluation using scaling factor between standard and non-standard
small-sized specimens in advance15,53-55, otherwise,
the applied displacement on MTP specimen for representing SSFS testing
data will be under- or over- estimated, leading to a large amount of
inaccuracy in cyclic plasticity property evaluation. According to the
latest literature review, the authors have not yet noticed any published
work on this topic using finite element (FE) modelling approach to
evaluate scaling factor based on an advanced mechanics-based material
model, especially in high temperature LCF testing for non-standard
small-sized thin-plate specimen.
