Applied pressure through fluid to measure strain

In summary, the conversation discusses the possibility of using pressure sensors on a curved soft tissue, such as silicon, to measure strain. The attached image shows the setup and the question is raised about whether the sensors would all show the same pressure or if changes in pressure could reveal strain. Further details are provided about the two stages of the experiment and the use of sensors to take readings before and after each stage. The person also asks for additional resources to further research this topic.

Hello,

I would like to ask if its possible to apply pressure through fluid on a curved soft tissue such as silicon to measure the strain by using sensors (and what kind) such as shows in the attached image?
If those were pressure sensors would they all show the same pressure or would the change of pressure could create a picture of the strain.

Additional details:
Stage 1 is before applying pressure
Stage 2 is after applying pressure
The sensors take readings before and after stage 1 & 2

Any more direction to research and read would be appreciated as well

Thanks!

If I have understood your diagram correctly.. all the sensors would read the same pressure.
 

1. What is the principle behind using fluid pressure to measure strain?

The principle behind this method is based on the relationship between fluid pressure and volume. When pressure is applied to a confined fluid, it will result in a change in volume. This change in volume can be measured and correlated to the strain applied to the object.

2. How is fluid pressure applied in this method?

Fluid pressure is typically applied through a hydraulic system, where a fluid-filled chamber is connected to the object being measured. As pressure is applied to the fluid, it will transfer to the object and cause it to deform. The resulting change in volume of the fluid is then measured to determine the strain on the object.

3. What types of materials can be measured using this method?

This method is suitable for measuring strain in a wide range of materials, including solids, liquids, and gases. It is commonly used in industries such as aerospace, automotive, and civil engineering to measure strain in materials such as metals, composites, and concrete.

4. How accurate is this method of measuring strain?

The accuracy of this method depends on various factors such as the sensitivity of the equipment used, the type of fluid used, and the calibration process. Generally, this method can provide accurate and precise measurements of strain with a margin of error of less than 1%.

5. Are there any limitations to using this method?

One limitation of using fluid pressure to measure strain is that it requires a confined space to apply the pressure. This may not be feasible for objects with irregular shapes or in certain environments. Additionally, the equipment and setup for this method can be costly and time-consuming, making it less practical for some applications.
