SUMMARY

The measurement of squishiness in materials like rubber is effectively conducted using a Shore durometer, which quantifies the hardness based on the depth of indentation made by a spring-loaded pin. Hooke's Law (F = -kx) can be applied to understand the force required for compression. Various scales exist for rubber due to its diverse properties, and specific tips are utilized for accurate readings. The process involves pressing a rounded surface into the rubber until a consistent reading is achieved.

PREREQUISITES
  • Understanding of Hooke's Law and its application in material science.
  • Familiarity with the Shore durometer and its measurement scales.
  • Knowledge of material properties, specifically regarding rubber.
  • Basic skills in using mechanical gauges for measuring force and indentation.
NEXT STEPS
  • Research the different types of Shore durometers and their specific applications.
  • Learn about the various scales used for measuring rubber hardness.
  • Explore the principles of Bulk Modulus in relation to material compressibility.
  • Investigate alternative methods for measuring material squishiness, such as using digital force gauges.
USEFUL FOR

Material scientists, engineers, product designers, and quality control professionals involved in testing and evaluating the properties of rubber and similar materials.

Hi, i wanted to know how you measure the squishiness of something, like a small piece of rubber. Is there some sort of tool that does this?

Maybe you can use Hookes law F=-kx. use a spring and push on the material and see how much force was required to compress the material a certain distance.

Pantaz called it right. You measure "squisheyness" with a gauge that presses a rounded surface into the rubber under test. The pin is spring loaded, and as the rubber presses the pin back towards the gauge, an indicator gives a readout. As I recall, this continues until the surface around the pin eventually meshes with the rubber. Then you record the reading.
Since rubber varies widely, there are different scales and corresponding tips that you can use.
