Abstract

ABSTRACT: Thermally induced behavior of a rod under the influence of a moving heat source is studied in the present work. The thermal behavior is modeled using the non-Fourier heat conduction model and the elastodynamic behavior of the rod is modeled using the nonlocal continuum mechanics. Laplace transformation and Riemann-sum approximation methods are used in the mathematical formulations. Based on the temperature history, the thermally induced nonlocal deformation and nonlocal stress behavior of the rod are studied. The influences of nonlocal scale parameter and speed of the heat source are studied in detail. The results presented in this work are helpful in the design of nanoscale welding, grinding, metal cutting devices, etc., that make use of the thermodynamic behavior within the nanoscale rod.
