Digital Image Correlation in Composite Testing

Join us for an enlightening webinar on the applications and techniques of Digital Image Correlation (DIC) in the field of destructive characterization of structural materials. DIC offers a powerful solution for visualizing deformations and strains in large areas of objects under varying loading conditions, making it a versatile and valuable non-contact metrology tool.

This seminar focuses on the theory and practical application of DIC in mechanical characterization, specifically for advanced fibrous composite laminates subjected to quasi-static loading. The goal is to provide participants with essential guidelines and best practices for planning, conducting, and evaluating DIC measurements in conjunction with mechanical testing of planar test specimens in general-purpose laboratory conditions.
