The true axial and lateral strains were calculated from the length-width data obtained from the video extensometer
Automatic synchronized video extensometer
and supply equipment in accordance with the procurement of technical specifications and draft contract terms.
This provider of testing equipment designed to evaluate mechanical properties of materials and components has introduced its HOM (hand-operated marker), said to be an innovative device designed for use with the company's non-contacting video extensometers
Although small pieces of cloth were glued to the surface of the specimen to prevent damage by the extensometer
knife edges, the location of fracture was mostly where the extensometer
A piezoelectric load cell was used to record the load data and an optical extensometer
with optical fiber as position indicator on the specimen was used to record the displacement data.
Figure 2 shows typical stress-strain behavior of a PC/C fiber PEEK composite with the extensometer
centered around the interface ([[lambda].

with replaceable inserts pcs 3 pcs, the estimated value of the object of the contract 32 400 EUR excluding VAT.
4-mm gauge-length extensometer
can grossly underestimate the local strain in the failure region once strain localization sets in, so that the significance of the reported failure strains [[epsilon].

5% of the diameter, where an extensometer
was mounted during the test to monitor the change of the cross-sectional diameter.
A commercially available and accurate video extensometer
has achieved BS: EN: ISO 9513 class 0.
Unlike traditional extensometers
, where users have to know where to place the extensometer
prior to the test, the DIC software maps the entire specimen surface and records full-field information, allowing users to draw virtual extensometers
anywhere on the specimen after the test.
