stress analysis

Stress Analysis Strain Gages (Gauges)

Structures can, and do, break. 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. Micro-Measurements’ complete portfolio of high-performance Stress Analysis Strain Gages deliver strain data you can count on and help you find practical solutions to prevent potentially catastrophic events.

Frequently Asked Quetsions about Strain Gauges

A strain gauge is a device used to measure strain or deformation in an object or structure. It consists of a thin metallic or semiconductor strip that changes its electrical resistance when subjected to mechanical strain. By measuring this change in resistance, the strain gauges provide a quantitative measurement of the strain experienced by the object.

Strain gauges find applications in various industries, including aerospace, automotive, civil engineering, structural analysis, materials testing, and research. They are used for stress analysis, load monitoring, product testing, fatigue testing, and deformation analysis in components, structures, and machinery.

When choosing a strain gauge, consider factors such as the material to be bond to, the expected strain range, temperature conditions and environmental factors. It is essential to choose a strain gauge with the right measurement factor, resistance and dimensions to suit your specific measurement requirements. In this regard, our team of experts will be happy to assist you so that you can be assured of a successful installation.

Most strain gauges are attached to the surface of the object being measured with a special adhesive (depending on application and environmental factors). Proper surface preparation, including cleaning and roughening, is crucial for reliable adhesion. In addition, it is essential to follow the manufacturer’s guidelines for bonding and wiring for accurate measurement.

The gauge factor is a key parameter that characterizes the sensitivity of a strain gauge. It represents the fractional change in electrical resistance per unit strain. By knowing the gauge factor, you can calculate the strain based on the measured change in resistance.

Yes, strain gauges can measure both static and dynamic strain. However, dynamic measurements often require specialized techniques and equipment to capture fast-changing strains accurately.

Yes, strain gauges are available in different types and configurations to suit various environmental conditions. For harsh environments with high temperatures, corrosive chemicals, or extreme vibrations, there are strain gauges specifically designed to withstand these conditions.

Yes, strain gauges can be used on a wide range of materials, including metals, composites, plastics, and ceramics. However, the preparation and bonding techniques may vary depending on the material’s properties.

Strain gauges are calibrated using known loads or strains. Calibration involves applying a known force or deformation to the structure, measuring the corresponding strain using the strain gauge, and comparing it to the expected values. Calibration ensures the accuracy and reliability of the strain gauge measurements.

Strain gauges are typically designed for single-use applications and are challenging to remove without damaging them.
