摘      要：The effective properties of composite materials have been predicted by various micromechanical *** composite materials of constituents which are described by the classical governing equations of the local form,the conventional micromechanical schemes usually give effective properties of the local ***,it is recognized that under general loading conditions,spatiotemporal nonlocal constitutive equations may better depict the macroscopic behavior of these *** this paper,we derive the thermo-elastic dynamic effective governing equations of a fibre-reinforced composite in a coupled spatiotemporal integral *** coupled equations reduce to the spatial nonlocal peridynamic formulation when the microstructural inertial effects are *** static deformation and steady-state heat conduction,we show that the integral formulation is superior at capturing the variations of the average displacement and temperature in regions of high gradients than the conventional micromechanical *** approach can be applied to analogous multi-field coupled problems of composites.
