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.

Residual stress measurement by strain gauge and X-ray diffraction method in different shaped rails

Engineering Failure Analysis, 2019
It is well known that rails are the most important part of railway infrastructure. Besides good wear and fatigue resistance, appropriate residual stress value in rails is required to improve performance of rails.

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 ...
