Abstract The primary purpose of the current study is to develop the constitutive relations for an isotropic fissured porous solid and an anisotropic fiber-reinforced material in the context of Eringen's nonlocal elasticity theory and to execute the investigation regarding the dynamic response of a layered composite system caused by a load moving on the upper rough surface with parabolic irregularity. The composite model is constructed by an overlying irregular incompressible nonlocal functionally graded fissured porous material (FGFPM) layer saturated with non-viscous fluid imperfectly bonded to a nonlocal fiber-reinforced material (FM) half-space. On the basis of suitable boundary conditions and perturbation technique, the local and nonlocal shear and normal stresses are accomplished in closed analytical forms. Graphical illustrations are presented on the basis of frictional coefficient, porosity, functional gradient parameter, irregularity factor, irregularity depth, nonlocality parameter, and bonding parameters.
Highlights The local and nonlocal stresses of a layered model due to moving load are deduced. The model comprises an overlying irregular nonlocal FGFPM layer imperfectly bonded to a nonlocal FM substrate. Eringen's nonlocal theory is applied to develop the constitutive relations for the considered materials. Variations in nonlocal stresses are represented graphically with respect to several key parameters.
