Extensometers for Mechanical Testing <---
Fracture Mechanics Clip-On Gages Model 3541
For fracture mechanics studies, these COD meters are in accordance with standard test methods, such as ASTM E1820 for the determination of fracture toughness properties of metallic materials. These meters conform to the requirements of E1820 (the replacement for the E813 and E1737) for JIC and R-curve determination.
Special configurations are available to meet ASTM E399 requirements for fracture strength (please consult factory for these configurations). Additionally, the modified slot design meets E1820 tests where there is increased stability and accuracy in the root of the slot results.
Clip-on type gages are used for a variety of fracture mechanics tests, including compact stress, arc shape, disc shape, bend samples, and other sample geometries in compliance with ASTM and other Organizational Standards. of test test methods.
Clip-on gauges can be used directly on test specimens where the edges of the blades are integral with the test specimen or, alternatively, with blade edges mounted on the test specimen.
The Model 3541 strain gauges are strain gauge devices, which are compatible with any electronic apparatus designed for strain gauges. They are often connected to a testing machine controller. Signal conditioning electronics for the extensometer are typically included with the testing machine controller or can often be added. In this case, the extensometer is supplied with the appropriate connector and wiring to connect directly to the electronics.
For systems that lack the necessary electronic components, Epsilon can provide a variety of solutions, allowing extensometer output to be connected to data acquisition cards, graphic recorders, or other equipment.
