Abstract: | A number of hypotheses were formulated using the properties of an asymptotic solution of boundary-value problems of the three-dimensional
micropolar (moment asymmetric) theory of elasticity for areas with one geometrical parameter being substantially smaller than
the other two (plates and shells). A general theory of bending deformation of micropolar elastic thin plates with independent
fields of displacements and rotations is constructed. In the constructed model of a micropolar elastic plate, transverse shear
strains are fully taken into account. A problem of determining the stress-strain state in bending deformation of micropolar
elastic thin rectangular plates is considered. The numerical analysis reveals that plates made of a micropolar elastic material
have high strength and stiffness characteristics. |
