DIC strain measurement has many advantages versus traditional extensometer or laser extensometer
With the need for improved measurement accuracy, new extensometers such as the non-contact laser extensometer
have begun to replace the use of crosshead travel as a means of displacement measurement, dramatically improving the quality of tensile-test data.
Tinius Olsen Testing Machine Co., Willow Grove, Pa., will introduce its new pushbutton-controlled 10,000-lb capacity Series 10000 Universal Testing Machine, equipped with the company's new advanced 70H 500L Scanning Laser Extensometer
and the latest version of the company's software.
The newsletter also focuses on the machine's laser extensometer
, another optional capability.
An Applied Test Systems (ATS) direct tension tester (DAT) provided with an Electronic instrument Research laser extensometer
Model LET-01 and an ATS environmental chamber were used to perform this test.
Duplicate testing was done at a strain rate of 5 mm/minute at room temperature on a T-2000 testing machine with a laser extensometer
based on marks 12.7 mm apart.
