WebMar 13, 2024 · Stress-Strain Curve In a standard test to study the tensile properties of a metal a wire is stretched by the applied force. The fractional change in length (strain) and the applied force needed to cause the strain are recorded. This force is gradually increased and the change in dimensions is noted. WebThe proposed method was tested on custom-made tissue-mimicking phantoms. Mechanical compression testing was conducted on the samples made of the same material as the phantoms and taken as the reference. The stress-strain curves for the same material from the proposed method and from mechanical testing are in good agreement. in touch capital markets llc https://jbtravelers.com
