DOI: 10.1007/s00161-018-0691-1
Abstract: An ordinary state-based peridynamic model is developed for transient fully coupled thermoelastic problems. By adopting an integral form instead of spatial derivatives in the equation of motion, the developed model is still valid at discontinuities.… read more here.
