Stress-Strain Measurement of the Spinal Cord of Puppies and Their Neurological Evaluation

The Journal of Trauma: Injury, Infection, and Critical Care, 1981
An in-vivo experiment was developed to identify the biorheological properties of the spinal cord of puppies under uriaxial deformation. For strain less than 4.5%, the ratio between stress and strain was about 2.65 x 106 dyne/limbs of the puppies were recoverable after the spinal cord segment at L1 was stretched once by 10-50%.

Stress-strain hysteresis cycle measured by a differential self-mixing interferometer

2006 Conference on Lasers and Electro-Optics and 2006 Quantum Electronics and Laser Science Conference, 2006
An instrument for non-contact measurement of differential displacements is realized based on two self-mixing laser diode interferometers. Stress-strain hysteresis cycles in micro- and gross-slip regimes of two metal samples kept into contact are measured.

Measurement of Compressive Stress-Strain Response at Small-Strains

Journal of Visualized Experiments
This study developed a measurement method capable of precisely evaluating the mechanical behavior of materials and microdevices in the small-strain region. The system integrates a motor-controlled z-stage, a microcontroller board, an operational amplifier circuit, and a force sensor, enabling synchronized force-displacement acquisition through custom ...

The Stress‐Strain‐Relation of Elasticity and the Measure of Strain

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1960
AbstractThe stress‐strain relation of elasticity which is independent of the measure of strain contains the straintensor in zero, first and second order and an infinite number of scalar parameters. When the displacement gradient is infinitesimal, the relation is reduced to sik = (λI + δII) δik + 2μ δik + 4μc ϵiα ϵαk with the four constant scalar ...

Measures of Finite Strain and Stress-Strain Relations

Journal of the Physical Society of Japan, 1960
Ordinarily, stress-strain relation of Lagrange's representation is written in terms of Lagrange's representation of stress σ i j and the Love measure e i j L . From the above relation, we can derive Reiner's equation in terms of Euler's representation of stress T λµ and the Green measure e λµ β .

Measurement of Stress-Strain Properties of Tendon with Ultrasound Parameters

2010
Quantitative ultrasound (QUS) measurements have been proposed for quantitative evaluation of bone tissue noninvasively. It also demonstrated to have the potential to evaluate the properties of tendon. Stress strain properties of tendon are important information for many clinical applications, such as monitoring the recovering progression of surgery or ...

Introduction to Stress-Strain Relationship and Its Measurement Techniques

2020
In this chapter, the basic concepts of strain and the subject of components deformation and associated strain is proposed to be briefly discussed. The strain is a pure geometric quantity so there will be no limitation on the material of the component is required. The significant aspects related to strain and stress-strain relationship briefly discussed

Measurement of stress‐strain relationship and stress relaxation in various synthetic ligaments

Knee Surgery, Sports Traumatology, Arthroscopy, 1994
AbstractIn an experimental study various synthetic augmentation devices for knee ligament surgery were tested in a servo‐mechanical universal tensile testing machine under uniaxial loading. Two tests were done to elucidate the mechanical behaviour: stress relaxation and stress‐strain relationship.

Cyclic stress-strain measurement tests of Sn3.5Ag0.75Cu solder joint

Proceedings of the 4th International Symposium on Electronic Materials and Packaging, 2002., 2003
For an accurate measurement of the material behavior of solder joints, a test method was established to calibrate the machine stiffness. Also another new optical experimental technique to measure the deformation across a solder joint is proposed. The test method uses the dual microscope that can measure the relative deformation of two adjacent regions.
