Abstract
A micro-tensile testing system providing a stand-alone test platform for testing and reporting physical or engineering properties of test samples of materials having thicknesses of approximately between 0.002 inch and 0.030 inch, including, for example, LiGA engineered materials. The testing system is able to perform a variety of static, dynamic, and cyclic tests. The testing system includes a rigid frame and adjustable gripping supports to minimize measurement errors due to deflection or bending under load; serrated grips for securing the extremely small test sample; high-speed laser scan micrometers for obtaining accurate results; and test software for controlling the testing procedure and reporting results.
Claims22
A testing system for testing a property of a test sample of a material, the testing system comprising:
- a frame;
- a gripping support coupled with the frame and adapted to secure the test sample;
- a drive mechanism adapted to apply a load to the gripping support and the test sample;
- a microstepping drive coupled with the drive mechanism and operable to provide constant loading of the test sample to test tensile strength, the constant loading providing a generally uniform force per minute to the test sample;
- a laser micrometer adapted to measure as first test data a change in the test sample during testing;
- and
- a load cell having a value and adapted to record as second test data the load applied to the test sample during testing.
A testing system for testing a property of a test sample of a material, the testing system comprising:
- a frame;
- a gripping support coupled with the frame and adapted to secure the test sample;
- a drive mechanism adapted to apply a load to the gripping support and the test sample;
- a laser micrometer adapted to measure as first test data a change in the test sample during testing;
- and
- a plurality of load cells each having a different value associated therewith, a first load cell being adapted to record as second test data the load applied to the test sample during testing, wherein the first load cell is removable and replaceable with a second load cell.
A testing system for testing a property of a test sample of a material, the testing system comprising:
- a frame;
- a gripping support coupled with the frame and adapted to secure the test sample, wherein the gripping support includes an interchangeable metal insert to facilitate alignment of the test sample on the frame;
- a drive mechanism adapted to apply a load to the gripping support and the test sample;
- a laser micrometer adapted to measure as first test data a change in the test sample during testing;
- and
- a load cell having a value and adapted to record as second test data the load applied to the test sample during testing.
A testing system for testing a property of a test sample of a material, the testing system comprising:
- a frame;
- a gripping support coupled with the frame and adapted to secure the test sample, wherein the gripping support includes an interchangeable metal insert to allow for further aligning the test sample on the frame;
- a drive mechanism adapted to apply a load to the gripping support and the test sample;
- a microstepping drive coupled with the drive mechanism and operable to provide constant loading of the test sample to test tensile strength, the constant loading providing a generally uniform force per minute to the test sample;
- a laser micrometer adapted to measure as first test data a change in the test sample during testing;
- and
- a plurality of load cells each having a different value associated therewith, a first load cell being adapted to record as second test data the load applied to the test sample during testing, wherein the first load cell is removable and replaceable with a second load cell.
