Stress Analysis Strain Gauge
Structures can, and do, break, and this may be important and sometimes dramatic. It’s critical to determine whether a particular object made from a particular material can carry a particular load. If a true stress is ignored, the cost of not acting is usually far higher than the cost of dealing with the problem earlier. A well-done strain measurement will produce an accurate representation of the strain actually present under the sensor. Strain data, however, is seldom gathered as a means unto itself. It is usually little more than a convenient vehicle for indirectly obtaining information about some other engineering parameter.
