Overview

Investigates how flaw geometry influences crack propagation and mechanical properties in granite under different loading conditions, highlighting structural safety implications.

Key Points

  • The research aims to explore how varied flaw geometries and loading conditions affect crack evolution in granite.
  • Analyzed five distinct flaw geometries in granite specimens under monotonic and cyclic loading.
  • Utilized Digital Image Correlation (DIC) for high-resolution monitoring of crack development.
  • Conducted tests with a stress amplitude of 75%, 80%, and 85% of peak uniaxial compressive strength.
  • Flaw geometry significantly influenced crack coalescence paths and failure patterns.
  • Transition from non-overlapping to overlapping flaws shifted crack trajectories from indirect to direct.
  • Cyclic loading introduced new cracks and altered the propagation paths at lower amplitudes.
  • Specimens with overlapping flaws showed higher strength and crack initiation stress ratios under monotonic loading.
  • Fatigue life decreased with increasing loading amplitudes, with S180 demonstrating non-linear behavior.
