2D Strain Mapping Using A Video Extensometer

Tinius Olsen's  2D strain mapping option software is available for existing and new video extensometer installations for use with the Standard and Advanced software products. 2D strain mapping is used to give a graphical representation of the strain amounts varying across a specimen during a test, illustrating the non-uniform strain taking place.

Typically users take these pictures and include them in report analysis and conclusions alongside standard results and graphs adding to the data and overall analysis of a material or components performance under load.
