Strain gages feature in a large portion of the residual stress measurements we perform at Hill Engineering, which is why we pride ourselves on our ability to correctly choose and apply strain gages to fit any measurement needs.Continue reading New Vlog: How To Apply A Strain Gage
Strain gages are devices used to measure strain on the surface of an object. These strain measurements can be used to infer the amount of stress induced on the object, as is done with many types of residual stress measurements.
Additionally, strain gages can be used to measure things such as aircraft wing deflection, bridge cable creep, and tensile testing for material properties, making them an ideal tool for in-field measurements.
Strain gages come in many shapes and sizes and can measure strain in a single direction or in multiple directions, depending on the goal of the experiment. Strain gages can be used on a wide variety of materials under many conditions, such as in extreme temperatures or underwater.
Hill Engineering has extensive experience with strain gage application and can help design the experiment needed to reach your project’s goals. Strain gage application can be performed in our laboratory or at your site, to your specifications.
Strain gage application is useful for:
- Applications requiring in-field measurements with portable equipment
- Measuring strain in multiple directions
- Parts in every shape and size – nothing is too big or too small
- Measuring residual stress
If you’re interested in how we apply a strain gage to a simple specimen, watch our video:
Strain gages are a key component of many of the residual stress measurements that we perform at Hill Engineering. These small but mighty sensors can also be used for other experiments, and this is something that we highlight in our recent case study.Continue reading Case Study: strain gaging services
We’re putting something in a bottle, and no, it’s not an SOS to the world. It’s a strain gage!
Hill Engineering has recently developed technology to orient and apply strain gages inside a pressure vessel with restricted interior access. Continue reading Strain gage in a bottle
This week, we have uploaded a new vlog to Hill Engineering’s YouTube channel revolving around a particularly handy residual stress measurement technique. The hole drilling measurement method is one of our most popular residual stress measurement options, and involves the incremental drilling of a small hole into the surface of a specimen. Watch the video below and read on to learn more about the hole drilling method. Continue reading Hole drilling residual stress measurement method
Strain gages are key tools when performing residual stress measurements. By tracking the electrical resistance change of the strain gage foil, we can evaluate strain through material deformation. In our vlog presented below, we demonstrate how to apply a strain gage on an aluminum tensile specimen. While the setup described in the video is simple, we are capable of applying strain gages to much more complex geometries to fit the needs of our residual stress tests.
