Tensometric

Tensometric refers to the measurement of strain, which is the deformation of a material in response to applied stress. This is typically achieved using a strain gauge, a sensor whose electrical resistance changes proportionally to the amount of strain it is subjected to. When a material deforms, the strain gauge attached to it also deforms, altering its resistance. This change in resistance can be measured and correlated to the applied stress.

The principle behind tensometric measurements is based on the piezoresistive effect, where the electrical resistivity of a material changes with applied mechanical strain. Strain gauges are often made of thin metallic foil or semiconductor materials arranged in a grid pattern to maximize sensitivity and provide a measurable resistance change. They are bonded to the surface of the object being measured.

Tensometric techniques are widely used in various engineering and scientific fields. Applications include structural health monitoring of bridges and buildings, load cell calibration, material testing, aerospace applications, and automotive systems. By accurately measuring strain, engineers can assess the integrity and performance of components under stress, ensuring safety and optimizing designs. The data obtained from tensometric measurements is crucial for understanding material behavior and predicting potential failures.
