Demonstration of the Tensilkut II

June 23, 2015

The Tensilkut II is used to easily prepare flat tensile, compression, flexural and other specimens from metals and non-metallics.  This machine is designed for operation in the testing lab by technicians without previous machining experience.

The starting blank is inserted into the Tensilkut Master Template, and the clamping screws are tightened as shown in this video.  The micrometer dial on the Tensilkut control head is set to its starting position, and a series of light passes are taken to cut the material from each side of the specimen.  When the correct tensile specimen dimensions are achieved, the micrometer dial will stop turning, thus preventing cutting an undersized test specimen.  After removing the completed ASTM E8 or other specimen from the master template, the tensile bar is ready for immediate testing.

ASTM D5379 Shear Samples

August 16, 2013

Recently, Tensilkut was asked to develop a method to prepare samples in accordance with ASTM D5379 for Shear Test Samples with a V-notch on either side.  These samples are to be used with the Iosipescu Shear Test Fixtures, as supplied by major testing machine manufacturers.  This test method for composites was developed during the 1980s, and the ASTM specimen was finalized in 1993.  The standard specimen is 3″ by .75″, and can be up to 1/2″ thick.  Identical notches are cut into either side of the specimen for accurate testing.  Tensilkut Engineering has developed a new machine specifically for preparing samples to ASTM D5379.
