Abstract

This study presents a peridynamic (PD) modeling approach for non-Fourier heat conduction and non-Fickian moisture concentration in a finite element framework by considering MATRIX27 elements native to ANSYS. The thermal and moisture fields are coupled in the form of Dual-Phase-Lag (DPL) models to resolve the issue of propagation of thermal wave and mass of moisture with infinite speed. The nonlocal effects arising from thermal inertia, moisture inertia and microstructural interaction are included through the peridynamic form of the coupled field equations. The nonlocal PD theory involves integral equations without smoothness requirement of the field variable. Thermal and hygro bonds in PD enable exchange of thermal energy and moisture between nodes. The efficacy of this approach is established by considering heat conduction in a nanoscale metal film and a bar subjected to sudden pulse of thermal and moisture conditions.
