Abstract

Fringe patterns can be optically generated by the different developed optical methods or computer generated. This study tackles down one of the more difficult aspects of classical fringe pattern analysis, pattern unwrapping. Discontinuous patterns such as the microscopic displacement/strain fields of a particulate composite and shear bands are studied.

Keywords

Unwrapping of singular fringe patterns Determination of displacements and strains Particulate composites Shear bands
