THERMOELASTIC STABILITY OF A FINITELY DEFORMED SOLID UNDER NONCONSERVATIVE LOADS.
Abstract
The paper considers local thermoelastic stability of a finitely deformed solid with internal dissipation, under conservative and nonconservative surface tractions. In particular, stability under circulatory forces are discussed in detail. It is shown that, when nonconservative external forces are also present, the usual Pearson-Hill energy criterion for stability must be supplemented by another inequality which stems from the entropy-balance equation. The relation between this inequality, which is trivially satisfied only if the external load is conservative, and Liapanov's stability criterion is discussed. (Author)
