Optical Strain Measurement for Model Validation

3D Digital Image Correlation provides complete full-field measurement of 3D shape, displacements, strains. These full-field results can be directly compared to the computer models for fast, precise and efficient model validation. The power and savings of these efforts can lead to improvements towards lean design and manufacturing.
● How optical 3D displacement and strain measurements provide rapid and precise analysis of materials and structures.
● How noncontact optical strain measurements can provide full-field results on all materials from ceramics to thin films, and for understanding complex structures like composites, biomaterials and other non-isotropic materials.
● How to achieve efficient analysis of complex structures as well as the true interface effect of each component.
● Why, when combined with optical thermal measurement, full-field strains can be corrected for thermal expansion, providing true mechanical strain measurement.
