Formation of lithosphere's plates owing to loss of stability of deformation under the influence of the internal pressure and forces of inertia of rotation

Abstract

Local changes of thickness of a lithosphere are caused by instability of deformation of an ellipsoidal lithospheric cover of Earth under the influence of the internal pressure and volume forces of inertia of rotation.Stability of deformation is investigated by a Leybenzon-Ishlinsky method.The main stressed and deformed state is considered at an invariable form of border of a body, and revolted taking into account turns of elements of borders of a body in the course of transition to an adjacent form of balance.
