摘要

The boundary value problem of general three-dimensional asymmetrical (momental) theory of elasticity for a thin shell is considered. It is assumed that the general stress-deformed state has resulted from interior stress-deformed state and boundary layers. An asymptotic method of integration of three-dimensional boundary value problem of asymmetrical theory of elasticity is applied for approximate computation of the interior stress-deformed state and boundary layers. Depending on the values of dimensionless physical parameters of shell's material, three various asymptotics are constructed. Initial approximation, correspondingly, for the first asymptotics brings to the general theory of micropolar thermoelastic shells with independent rotation, for the second asymptotics-to the general theory of micropolar thermoelastic shells with constraint rotation, and for the third asymptotics-to so-called theory of micropolar thermoelastic shells with "small shift rigidity". Corresponding micropolar thermoelastic boundary layers are constructed and studied. The areas of application of the constructed theories of thermoelasticity of micropolar shells are presented.
