“…A similar approach was presented in [8], where analytical results were compared with the numerical model. The core anisotropy certainly is of particular importance in the case of non-uniform boundary conditions [9]. It is worth noting that the determination of the anisotropic parameters of the core is a very difficult issue.…”

Abstract. The paper concerns the phenomenon of wrinkling of compressed facing of a sandwich panel. The parametric analysis of the numerical model of the sandwich panel with a soft core is presented. The core was assumed as an elastic orthotropic material. The results of numerical simulations show the sensitivity of a sandwich structure to the variations of the core parameters. The results are evaluated qualitatively and quantitatively.

“…Kahina Saad Saoud [19] considers the problem of general and local loss of compressed facing. Robert Studziński [20] explores the impact of microprofiling of facing on the bearing capacity of sandwich panels. Bronisław Kosowski [21] in his article offers calculation of multispan sandwich panels with intermediate supports elastic pliability under the influence of uniformly distributed load and stress caused by the difference in temperature.…”

Abstract. This paper considers the issue of sandwich panels using as load-bearing structural elements. The comparison of deflections and critical failure loads were obtained by the results of the full-scale roof sandwich panels tests conducted by the company "Joris Ide" and the theoretical design, according to the calculation method described in Euronorms. Based on these results it was concluded that sandwich panels can be treated as a load-bearing structure only with more taught manufacturing requirements. Thus, the reduced spread of critical loads can be achieved.

“…Sandwich panel is a low-weight prefabricated product ready for an immediate assembly, which makes it easy to handle, transport and embed in the structure; it is also characterised by water impermeability, improved thermal properties and a relatively good bearing capacity. These advantages are the main reason why it is widely used in the building industry [3][4][5][6][7][8][9][10][11][12][13]. The most common types of panels used in civil engineering are composed of steel or aluminium facings and a polyurethane or expanded polystyrene foam core.…”

“…The most common types of panels used in civil engineering are composed of steel or aluminium facings and a polyurethane or expanded polystyrene foam core. Due to complexity of layer interactions even these widespread combinations of materials are of a great interest to researchers in terms of geometry optimisation (length, relative layer thickness, facing geometry) [3,4,14], localised load effects and varied support conditions [4][5][6][7], the influence of openings [8] or submission to extreme loads (windborne debris, explosions) [10,11]. Exchanging thin metal facings with relatively thicker, wood-based ones and using a foam core of a significant thickness created a sandwich panel variation called the Structural Insulated Panel (SIP).…”

Abstract. Sandwich panels are readily used in civil engineering due to their high strength to weight ratio and the ease and speed of assembly. The idea of a sandwich section is to combine thin and durable facings with a light-weight core and the choice of materials used allows obtaining the desired behaviour. Panels in consideration consist of MgO (magnesium oxide) board facings and expanded polystyrene core and are characterized by immunity to biological corrosion, a high thermal insulation and a relatively low impact on environment. Customizing the range of panels to meet market needs requires frequent size changes, leading to different failure modes, which are identified in a series of costly full-scale laboratory tests. A nonlinear numerical model was created with a use of a commercial ABAQUS code and a user-defined procedure, which is able to reproduce observed failure mechanisms; its parameters were established on the basis of small-scale tests and numerical experiments. The model was validated by a comparison with the results of the full-scale bending and compression tests. The results obtained were in satisfactory agreement with the test data.
