Implication

This methodology demonstrates high-speed imaging to compute full-field strains in polydimethylsiloxane, indicating finite deformations can be assessed accurately.

Key Points

  • Full-field strains were accurately measured using high-speed imaging, enabling the analysis of deformation in polydimethylsiloxane under mechanical loading.
  • The method achieved 100 Hz scan rate, significantly reducing image acquisition time compared to previous AFM studies.
  • Utilizing Digital Image Correlation, strains were assessed with just 0.5% error in mean strain, underscoring the method's precision and repeatability.
  • High-speed AFM as a quantitative tool opens new opportunities in studying the mechanics of soft materials, indicating its extensive applicability.
