Abstract
The objective of this paper is to show the application of moire fringes in the determination of strains in two-dimensional models. The moire pattern is interpreted as a function of displacements only from which strains in the Lagrangian and Eulerian descriptions are determined. This presentation is not limited to small deformations, and sets of formulas appropriate for every case are given here.Keywords
