Accounting for Localized Deformation: A Simple Computation of True Stress in Micropillar Compression Experiments
Résumé
Compression experiments are widely used to study the mechanical properties of materials at micro- and nanoscale. However, the conventional engineering stress measurement method used in these experiments neglects to account for the alterations in the material’s shape during loading. This can lead to inaccurate stress values and potentially misleading conclusions about the material’s mechanical behavior, especially in the case of localized deformation.
