Fracture Parameter for Thermoplasticity in the Case of Dilatation Symmetry
Source abstract
Abstract
An extension of the M integral to thermoplasticity related to the dilatational or scaling symmetry is presented. Based on a discrete Lagrangian describing the thermo‐inelastic system andon Noether's theorem defining the conservation law, the null Lagrangian theorem is applied in order to introduce thermoplasticity. By the use of the divergence theorem, the modified M integral is obtained.
