How Does Strain Gauge Measure Strain? A strain gauge is a sensor whose measured electrical resistance varies with changes in strain. … Strain gauges convert the applied force, pressure, torque, ect., into an electrical signal which can be measured. Force causes strain, which is then measured with the strain gauge by way of a change
What Is DIC Used For? Digital Image Correlation (DIC) is a precise, non-contact, and non-interferometric optical method used for measuring the displacement/deformation of a structural element/material subjected to external loading. What is a DIC machine? Stress Engineering Services uses Digital Image Correlation (DIC) to monitor and measure three-dimensional full-field deformations and strains. This non-contact optical
