In the microscopic field corresponding to the tensile deformation of a solid propellant, moiré patterns that show dislocations can be observed. The source of these dislocations is the heterogeneity of the material. A theoretical framework is presented for the analysis of the fringes. The theory includes the justification of the validity of the strain pattern obtained from the moiré fringes.

Abstract
In the microscopic field corresponding to the tensile deformation of a solid propellant, moiré patterns that show dislocations can be observed. The source of these dislocations is the heterogeneity of the material. A theoretical framework is presented for the analysis of the fringes. The theory includes the justification of the validity of the strain pattern obtained from the moiré fringes.File in questo prodotto:
