Overview

Randomized trial analyzes crack propagation in fracture simulations, suggesting improved accuracy and efficiency.

Key Points

  • The aim is to develop a hybrid finite element–peridynamics framework for accurate fracture simulation and crack propagation analysis.
  • Developed a modified volume-based coupling scheme for hybrid FE–PD systems.
  • Introduced a residual-based dynamic relaxation solver for quasi-static analyses without damping.
  • Validated against the classical Kirsch stress concentration problem to ensure accuracy.
  • Achieved 23 times faster computation than standard adaptive dynamic relaxation methods.
  • Reproduced correct quantitative crack distribution and morphology under Mode I loading with high accuracy.
  • Confirmed that crack branching does not occur under quasi-static loading at dynamic levels, consistent with classical mechanics theory.
