Area of Science:

  • Materials Science
  • Polymer Science
  • Mechanics of Materials

Background:

  • Directly quantifying spatially varying stress in soft materials remains a significant challenge.
  • Existing methods often lack precision or are difficult to implement for complex stress fields.

Purpose of the Study:

  • To develop and validate a novel optical method for direct stress quantification in soft materials.
  • To utilize force-activated mechanophores for visualizing and measuring stress distribution.

Main Methods:

  • Incorporation of spiropyran (SP) force-activated mechanophore cross-linkers into multiple-network elastomers.
  • Calibration of chromatic changes in response to uniaxial tension.
  • Optical detection and pixel-by-pixel analysis of stress around a loaded crack.

Main Results:

  • The activation of SP probes correlates with applied load, causing detectable color changes in the material.
  • Quantitative measurement of nominal stress around a crack was achieved.
  • Experimental results showed excellent agreement with finite element simulations.

Conclusions:

  • The proposed method provides a direct and innovative way to quantify stress in soft materials.
  • The optical readout using SP mechanophores offers a simple yet powerful tool for material analysis.
  • This technique has potential for comparing stress distributions across different soft materials.
