摘要: The paper investigates the effects of creep core material on geometrically nonlinear behavior sandwich panels with debond at one core–face interfaces within framework high-order panel theory (HSAPT). theoretical model accounts for viscoelasticity via an incremental exponential law that corresponds to rheological generalized Maxwell obtained from expansion relaxation moduli into Prony series. HSAPT structural modeling deformability in shear and through its thickness, as well large displacements facesheets. An time-stepping analysis is conducted, which time variations stresses, deformations, effects. governing equations stresses deformations fields thickness are derived, capabilities studied numerically. results show of...
