Dr.-Ing. Matthias J. Merzkirch - RISE Research Institutes of Sweden
Topics and Contents:
The seminar describes theory and application of Digital Image Correlation for selected standardized and common state-of-the-art tests, for the mechanical characterization of advanced fibrous composite laminates under quasi-static loading conditions. In order to obtain accurate and representative material data, it is important being minute and careful when planning, performing, and evaluating experiments. The purpose of this seminar is to provide good practice guidelines for setting up and conducting Digital Image Correlation measurements in conjunction with mechanical testing of planar test specimens in general-purpose laboratory conditions. A brief historical overview will be presented and many inherent difficulties of tensile, shear, flexure, and fracture testing of composite laminates are addressed where pertinent measurement issues are visualized with DIC. The more you see, the less you can hide. Digital Image Correlation offers a new look at old problems of structural mechanics of composite laminates, presenting a detailed insight into mechanical testing of complex materials with anisotropic behavior, which cannot be covered by point measurements.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
