When comparing experimental and numerical simulation results, in addition to the error percentages of peak strength and elastic modulus. Can we find Poisson’s ratio as it is mentioned it is not applicable when the failure is initiated and but can an one how can i find it
Poisson’s ratio is defined as the negative of the ratio of lateral to axial strain. If you make a history of these quantities, then you can measure the slope, and that is the Poisson’s ratio. Also, consider using the two packages {https://www.itascacg.com/software/material-modeling-support} and {https://www.itascacg.com/software/snbv-support-for-pfc} for your work. These packages provide such histories from which you can obtain the Poisson’s ratio and many other things, like tracking bond breakages (thought of as microcracks). Note that Poisson’s ratio is a concept that describes a linear elastic isotropic material; however, it is also used as an index to quantify the dilation associated with material damage.
