With very low sensitivity to vibrations, this hot mountable unit is ideal for the demanding requirements of strain controlled, elevated temperature axial testing and other common test methods. Gauge Lengths: 10 – 50 mm Measuring Ranges: 10% – 100%Model EDS-71V/EDS-71P Electrical Borehole Extensometer System. The Encardio Rite Model EDS-71V electrical borehole extensometer is a precision instrument designed to help civil engineers and geologists in the measurement of the deformation of rock mass and adjacent or surrounding soil.. The construction, operating principle, applications, and specifications of the .Method A is based on the increase in tensile stress during load application. In the linear elastic part of the tensile test, that is at the very beginning of the test, the rate of stress application must be between 1.15 and 11.5 MPa/sec (this corresponds to 10000 and 100000 psi/min).; However, it is clearly stated in ASTM E8 and ASTM E8M that these specifications and method do not .

Compression (6) Extensometer (6) Object Testing (4) Tension (30) . and ASTM tensile test standards for hard plastics and metal materials. QuickView. Add Bookmark.The measured values are transferred from the video extensometer to a tensile test machine through a digital or analog interface. The tensile testing machine can then record and post process every measurement in the same way as other strain sensors or gauges. . In one real-world example, an R&D lab performs tension and compression tests on a .

This extensometer can be attached to round and flat specimens to perform tensile, compression, and cyclic tests in environmental chambers up to 600°C with no cooling required. A quick attach kit for mounting on specimens is included. The device has a low operating force that prevents it from affecting the test.

The range of application of the digiClip clip-on extensometer is expanded even further by the number of different initial gauge lengths available and through the flexible change in measurement travel that can be switched from "Tensile . The process of testing materials with an extensometer is relatively simple: first, the material being tested is placed between the two fixed points on the base of the extensometer. Then, a force is applied to one end of the .Tinius Olsen introduces Vector a step change in extensometer technology capable of replacing multiple contacting and non-contacting sensors with a single, industry specific instrument.

Engineering stress–strain data from a compression test on a cylinder of 7075-T651 aluminum are given in Table P4.1. (These are representative data from the compression test of Fig. 4.4.) Strain measurements up to 4.0% are from an extensometer with a 12.70 mm gage length, and beyond this strains are approximated from crosshead displacements.This blog post covers some of the common questions on axial extensometers. The guidance is based on ADMET equipment. How is an axial extensometer related to my testing procedure? When force is applied on a material, stress is produced and this stress causes the material to deform in the direction of the applied force. Stress vs. strain graphsUnconfirmed Compressive Strength (UCS) stands for the maximum axial compressive stress that a specimen can bear under zero confining stress. Due to the fact that stress is applied along the longitudinal axis, the Unconfined Compression Test is also known as Uniaxial Compression Test. UCS is a parameter widely used in geotechnical design, but .1.3.3. On Test Control > End of Test, set the end of test criteria to a force higher than expected in a real test, but lower than the system capacity. 1.3.4. On Test Control > Data, set up data capture to have a data rate equal to or greater than the rate used in the method used to test specimens. Minimum rate should

The Advantage™ Video Extensometer (AVX) delivers the flexibility, accuracy and repeatability needed in applications where it is difficult to measure strain using conventional means. This video extensometer combines several features that make it an outstanding choice to measure axial and transverse strain on plastics, metals, and composites. The 50 kN capacity and the fully variable test speed of 0.2 to 51 mm/min make it possible to perform not only the CBR and Marshall tests, but many other applications as for instance Indirect Tensile test, Quick Triaxial tests, Unconfined and Uniaxial soil testing and, in general, all test to be performed under displacement control.
