Abstract Scope |
We study dynamic crack propagation and its interaction with thermal effects using a phase-field modeling approach. We develop a thermodynamically consistent free-energy-based formulation to study the thermomechanics of crack growth.
We implement the formulation in a finite element framework and study the effect of thermal effects and dissipation on the evolution of cracks at high velocities. |
