摘要：

The infinitesimal (local) stability of uniform beams and circular arches under the terminal nonconservative loading is studied. The nonlinear equilibrium with large deflections is expressed in a closed form. Then, the equations which govern a free motion about the equilibrium position are constructed. The eigenvalue analysis of the linearized system of differential equations with varying coefficients is performed by the finite element concept and the subdomain collocation method.
