A Physics-Guided Smoothing (PGS) method is introduced for processing Digital Image Correlation (DIC) measurements, explicitly eliminating non-physical strain patterns and improving the physical consistency of displacement and strain fields. This pre-processing step leads to a 20% reduction in the L2 error of learned material constitutive laws and enhanced generalizability for both isotropic and anisotropic materials.

Key insights

  • Integrating partial physics knowledge, specifically non-negative strain constraints, directly into the data smoothing process significantly enhances the physical consistency and quality of experimental DIC data.
  • Addressing and correcting physically implausible measurement artifacts, often overlooked by conventional denoising methods, is crucial for accurate and reliable learning of complex material constitutive laws.
  • The improved data quality from PGS enhances the ability of downstream data-driven models to discover physically interpretable features and generalize robustly across varying loading conditions and data resolutions.
