A thermodynamically consistent phase-field framework for viscoelastic fatigue fracture with dissipated-energy-driven toughness degradation

· · 来源:tutorial资讯

The story starts with quantum field theory, which is incredibly complex, but the simplified version is that even empty space is filled with fields that could govern the interactions of any quantum objects in or near that space. You can think of different particles as energetic excitements of these fields—so a photon is simply an energetic state of the quantum field.
