What is the minimum(or maximum) specimen thickness at which the thickness has an effect on the tensile test results for steels?

28 November 2021 1 8K Report

I am trying to understand the effect of specimenn thickness on tensile properties(YS,Ts & %Elongation) of steels.

I came across Oliver's equation (relation between %elongation and specimen thickness) seems to be used for specimen with Parallel Length/Width ratio >5.5

What is the effect of specimen thickness for specimen with Parallel Length/Width ratio
