摘要: The refined version of an applied theory is developed, that adopting the analytical solution bending problem three-layer plate arbitrary asymmetric structure under point loading. Local effects are investigated within scope discrete model, considering specific character soft filler elastic properties. Advantages expressions characteristics in a closed form: layer curvatures, displacements and stresses. These shown to be varied several fold according asymmetry parameters structure.
