Computer simulations reveal fatigue fracture mechanisms in disordered materials. Healing effects can increase material lifetime and introduce a fatigue limit, preventing macroscopic failure.

Area of Science:

  • Computational materials science
  • Solid mechanics
  • Disordered materials

Background:

  • Fatigue fracture is a critical failure mechanism in materials under cyclic loading.
  • Understanding microscopic mechanisms of damage accumulation and healing is crucial for predicting material lifetime.
  • Disordered materials exhibit complex fracture behaviors influenced by their heterogeneous structure.

Purpose of the Study:

  • To investigate the fatigue fracture of disordered materials using a discrete element model.
  • To simulate the influence of damage accumulation and microcrack healing on fracture.
  • To compare simulation results with experimental data for asphalt fatigue fracture.

Main Methods:

  • Development and application of a two-dimensional discrete element model for fracture simulation.

  • Simulation of diametric compression tests on disc-shaped specimens under constant external force.
  • Variation of the relative influence of damage accumulation and microcrack healing mechanisms.

    • Main Results:

    • Specimen lifetime exhibits power-law behavior for intermediate applied loads.
    • Microcrack healing significantly increases material lifetime, especially at lower loads.
    • A fatigue limit emerges below which macroscopic failure is prevented.

    Conclusions:

    • The discrete element model effectively captures fatigue fracture mechanisms in disordered materials.
    • Microcrack healing plays a vital role in enhancing material durability and establishing a fatigue limit.
    • Simulation results show good qualitative agreement with experimental findings on asphalt fatigue.
