Defining Strain Gauges
Strain gauges are sensors that measure the amount of deformation or strain experienced by an object. They work on a simple premise: when an object is subjected to stress, it undergoes deformation, which leads to changes in electrical resistance in the gauge affixed to it. The primary function of a strain gauge can be summed up into a straightforward definition — it detects and quantifies these changes in response to external forces.
To clarify further, when a strain gauge is bonded to a material, any tensile or compressive force leads to a change in the length and cross-sectional area of the gauge's material, thereby altering its electrical resistance. This shift in resistance is proportionate to the strain and can be precisely measured, making strain gauges indispensable in experiments and practical applications alike.
Historical Background
The journey of strain gauges dates back to the 1930s. The technology emerged from the need for accurate measurements in structural engineering and materials science.

Understanding the fundamental principles of strain gauges is paramount in grasping their entire operational spectrum. These principles lay the groundwork for how strain gauges function, the relevance they hold in various applications, and their continual evolution in technology. The relationship between mechanical deformation and the resulting strain sensed by the gauge, along with the role of the Wheatstone bridge circuit in quantifying these changes, form the backbone of strain gauge technology. By mastering these concepts, students and professionals can harness the full potential of strain gauges in their respective fields.
Mechanical Deformation and Strain
Mechanical deformation occurs when an external force is applied to an object, causing it to change shape or size. This alteration can be temporary or permanent, depending on the force applied and the material's properties. The deformation experienced by materials can be categorized mainly into elastic and plastic strains. The former is reversible, allowing materials to return to their original shape once the stress is removed, while the latter results in a permanent change.
Strain gauges are designed to measure these deformations accurately. When a strain gauge is adhered to a material, any deformation due to stress leads to a change in the gauge's resistance. This change can be precisely measured and used to calculate the amount of strain experienced.
To summarize:
- Deformation: Change in shape or size due to stress.
- Elastic strain: Temporary deformation that disappears when the stress is removed.
- Plastic strain: Permanent alteration of the material shape.
Understanding mechanical deformation is essential. It shapes how engineers assess material performance and helps in designing structures that can withstand environmental forces.
