Abstract A thermo-chemo-mechanically (TCM) coupled peridynamic (PD) model is proposed to analyze the crack
behavior in solids considering heat conduction, species diffusion, and chemical reactions. A PD theoretical
framework is established based on non-equilibrium thermodynamics. The influences of species diffusion
and chemical reactions on the Helmholtz free energy density and the subsequent formation and propagation
of cracks are distinguished by introducing the concentration of diffusive species and the extent of the
chemical reaction. Furthermore, inter-physics coupling coefficients are calibrated by equating the
corresponding field in the PD model to the continuum mechanics under the same condition. More >
