Product Details

Tensile Testing Machine 100kN Metallic Sheet and strip tensile strain hardening exponent ISO10275 ETM105DP-A
 
Description:
 
Auto tensile testing machine can meet with your test requirements for more specimens with high effeciency.
 
Typical specimens: Metals, building components, large fasteners, composites, wood products
 
Standard: ISO 10275
 
Metallic materials — Sheet and strip —Determination of tensile strain hardening exponent
 
This International Standard specifies a method for determining the tensile strain hardening exponent n of flat products (sheet and strip) made of metallic materials.
The method is valid only for that part of the stress-strain curve in the plastic range where the curve is continuous and monotonic (see 7.4). In the case of materials with a serrated stress-strain curve in the work hardening range (materials which show the Portevin-Le Chatelier effect, e.g. AlMg-alloys) the automatic determination (linear regression of the logarithm true stress vs. the logarithm true plastic strain, see 7.7) should be used to give reproducible results.
 
Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only edition cited applies. For undated references, the latest edition of the referenced document
(including any amendments) applies.

Test equipment
Tensile testing machine, verified and calibrated in accordance with ISO 7500-1:2004 and of class 1 or better. The method of gripping the test piece shall conform to the requirements of ISO 6892.
Extensometer, of class 2 or better (class 1 in the event of determination of the plastic strain ratio r, see ISO 10113) in accordance with ISO 9513:1999, for measuring changes in the gauge length.
Dimension-measuring equipment, capable of measuring the width and thickness of the parallel-sided section of the test piece to within the tolerances specified for these dimensions in ISO 6892.
 
Procedure

  • In general, the test shall be carried out at ambient temperature, i.e. between 10 °C and 35 °C. Tests carried out under controlled conditions, where required, shall be made at a temperature of (23 ± 5)°C.
  • The test piece shall be mounted in the tensile testing machine (see 5.1) so that the force can be applied axially in accordance with ISO 6892.
  • In the plastic range, the strain rate of parallel length shall not exceed 0,008 s−1, unless otherwise specified in the relevant standard. This rate shall be kept constant during the time interval over which the tensile strain hardening exponent is determined. If a proof strength or the yield strength is determined during the same tensile test, the strain rate for this determination shall be as defined in ISO 6892.
  • When n is determined over the whole uniform plastic strain range, the upper limit for these data points shall be immediately prior to the strain at which the maximum force occurs.
  • For materials with homogenous deformation behaviour (i.e. materials without upper and/or lower yield strength), the lower limit of the range over which n is determined shall not be lower than a point after which the final testing rate used for determining Rm has been achieved.

Frame

  •  Robust guidance columns with self-lubrication increase lateral stiffness and ensure linear crosshead travel. This results in accurate crosshead alignment thus reducing variability in measurement data and producing better overall accuracy

  • Pre-loaded ball screws and heavy duty bearings assure long life with zero backlash as well as linear low force and through zero performance. The result is accurate and repeatable measurements that truly represent the specimen characteristics rather than load frame deficiencies

  • Fully-protected lead screw covers provide longer life and greater operator protection

  • Easy-to-clean aluminum column covers with chamfered corners to facilitate access to the test area. T-slots are built in for simple, convenient attachment and positioning of testing accessories

Driving system

  • Japanese YASAKAWA AC servo motor and arc-shape silent synchronous belt features high-speed, low vibration, world-class, and maintenance-free

  • Germany NORD gear reducer offers low noise, low heating, and high efficiency

  • Photoelectrical encoder built in servo motor system is for position measurement of crosshead

Load cell

  • High- precision USA-made Interface load cell offers high stiffness, high stability, and high linearity
  • Over-load protection, lateral loading protection

  • Bi-direction allows tension and compression test

  • Self-recognition (TEDS) function

  • Regular self-calibration

  • Working temperature: -55℃~90℃

Controller:
   Imported Germany Doli controller with high quality.
 
Remote control with display
