Surface patterns on the test specimen are essential for Digital Image Correlation (DIC). If there are no sufficiently recognizable natural patterns on the surface of the specimen or if the surface is highly reflective, it is recommended to make use of artificial patterns, e.g. produced by spraying paint.
The StrainMaster Speckle Pattern Toolkit is an easy-to-use alternative to spray cans and conventional stamps.
A special foam roller allows the application of a particularly fine speckle pattern similar to that provided by aerosol paints. On larger areas patterns can be produced with the porous, soft rubber sponge. Multiple applications of the sponge to the specimen surface increases the density of the speckle pattern.
The paint used for the StrainMaster Speckle Pattern Toolkit is water-based with additives that ensure it adheres to plastic and metal surfaces. The paint is completely non-toxic and easily cleaned from the surface with soap and water!
The Airbrush Kit LaVision is offering consists of a matched compressor and head system to provide an exceptionally smooth transition from fine to medium spraying. The system offers exceptional atomization, performance and control. It provides a body cut out for easy seal access and cleaning and comes with a rugged metal storage case.
Additionally the Airbrush Kit also comprises a powerful, quiet and reliable oil free airbrush compressor fitted with a 2.5 l air tank which is enclosed in a sturdy steel case with carrying handle. This compressor operates to the demand of the air tank based on the automatic pressure control.
LaVision has years of experience in the application of artificial patterns, i.e. for high temperature applications or for experiments with large sample elongation. Please contact us for specific information.
