The response of a sandwich panel with bilinear constitutive behavior for shear stress of a core is presented based on a proposed improved extended high order sandwich panel theory. In this theory the face sheets are analyzed based on the first order shear deformation theory that is hitherto not applied in the conventional extended high order sandwich panel theory. Besides, the two-dimensional (2D) elasticity is used for the core. The field equations are derived using the Ritz-based solution which is suitable for any essential boundary condition. In each type of boundary conditions, the effects of plastic shear modulus of the core on transverse shear stress distribution within the core, transverse normal stresses at top and bottom face sheet–core interfaces, displacement components through the thickness of the core, as well as the force and moment resultants and transverse displacements in the face sheets are studied in detail. Also, all results based on the bilinear material assumption of the core are compared with the linear elastic ones. The results reveal that initial plastic regions are created at core edges. Furthermore, the absolute value of shear stresses in the plastic zones based on the bilinear analysis is lower than those obtained from linear elastic one for both types of the boundary conditions. It is seen that, unlike the case of the clamped edges, the plastic regions predicted by bilinear material behavior are much more extensive than ones resulted from elastic material behavior in the simply supported case. Finally, in the case of the linear elastic analysis, the results of the transverse deflections and shear stresses are compared with finite element simulation.

“…Aboura et al (2004) have proposed a model to study the elastic behavior of corrugated cardboard. The model shows that the EMD modulus and bending properties (D11 and D22) are strongly influenced by the total sheet thickness while the E CD modulus is more influenced by the grooving step and other studies such as those of Wan-Shu Chang and T. Krauthammer (2006), Kyung-Jo Park et al (2016), Cenk Kılıçaslan et al (2013), M.R.M. Rejab et al (2013), Xiaoxia Huang et al (2020).…”

Nowadays, numerical simulation methods have been widely applied in product design and development, especially in sandwich panel design. However, such numerical models need to be built to optimize calculation time. In this paper, we propose a finite element model to study the plastic mechanical behavior of corrugated sandwich panels. Accordingly, a 2D finite element equivalent model is built by the homogenization method to replace the 3D model. This model greatly reduces the computation time as well as the model building time. The accuracy of the proposed model is confirmed by comparing the numerical simulation results of the 2D equivalent model with the 3D model and experimental results.
