On the measurement of stress–strain curves by spherical indentation

Thin Solid Films, 2001
Abstract It has been proposed that with the appropriate models, instrumented indentation test (IIT) data can be reduced to yield the uniaxial stress–strain behavior of the test material. However, very little work has been done to directly compare the results from uniaxial tension and spherical indentation experiments.

Differential ultrasonic stress–strain measurements

The Journal of the Acoustical Society of America, 1999
Fatigue tests are often encumbered by lack of the specimen’s exact length due to mechanical grip effects and by environmental noise factors. Such issues may be mitigated when differential measurements are undertaken between consecutive data states. Our principle-monitoring tool is an ultrasonic pulse-echo process where the primary and secondary echoes ...

Measuring the Biaxial Stress-Strain Characteristics of Human Sclera

ASME 2007 Summer Bioengineering Conference, 2007
Glaucoma is a common ocular disease that causes irreversible loss of vision. Elevated intraocular pressure (IOP) is the primary risk factor for developing glaucoma. It is believed that increased IOP causes mechanical strain on the glial cells that support the retinal ganglion cell axons and thereby causes ganglion cell apoptosis [1,2].

Measurement of stress–strain and vibrational properties of tendons

Measurement Science and Technology, 2003
The authors present a new non-intrusive experimental procedure based on laser techniques for the measurement of mechanical properties of tendons. The procedure is based on the measurement of the first resonance frequency of the tendon by laser Doppler vibrometry during in vitro tensile experiments, with the final aim of establishing a measurement ...

Cell poker: An apparatus for stress-strain measurements on living cells

Review of Scientific Instruments, 1980
An apparatus is described which can make force vs. displacement measurements on regions of a living cell. A force on the order of 10−3 dyne is applied by a stylus to an area of about 10 μm2 on the upper side of a cell growing on a culture dish. The resulting deformation is deduced from a solution conductance measurement with a sensitivity of 0.1 μm ...
