Thermoelasticity of multilayered plates with imperfect interfaces

Three-dimensional exact solutions for temperature and thermoelastic stresses in multilayered anisotropic plates are derived advanced boundary-value problems with general boundary conditions. The extended Stroh formalism is formulated to include the thermal coupling Eringen nonlocal elasticity theory that captures small scale effects. simply supported structures subjected time-harmonic distributions of temperature, combined tractions, which represented by means Fourier series expansions. In particular, prescribed loads on both bottom top surfaces uniformly heterogeneously distributed normal stresses, while imperfect mechanical contacts between constituents incorporated at internal interfaces. Recursive field relations interfaces consistently articulated virtue traditional propagation matrix method, further completed dual variable position technique overcome numerical instability issues. Three application examples proposed throw light various effects externally applied imperfections fields structures. residual stress graphite fiber-reinforced epoxy composites shown be drastically different from those predicted classical when significant. stacking sequence number copper molybdenum laminated great importance tailoring interfacial properties, especially if thermally conducting boundaries taken into account. forced vibration analysis barrier coatings nickel based superalloys investigated, including bonding adjoining layers. Depending input frequency amplitude, severe oscillating displacements take place single crystal can endanger safety-related stability integrity aircraft engines. Overall, present should utilized optimal design sophisticated desired steady-state responses.
