Systems Manifesting Superposed Elastic and Viscous Behavior

摘要: Actual substances exhibit a very complicated behavior under mechanical stresses which cannot be described by classical elasticity theory nor the of hydrodynamics viscous fluids. A general molecular describing matter stress is discussed and related to previous investigations experimental observations. Particular attention devoted rubberlike for theories are definitely inadequate. Experimental results on relaxation creep rubbers interpreted in terms modern structural concepts. It found that these three regions stress‐temperature‐time dependence. At intermediate temperatures there exists region relative stability statistical‐thermodynamic rubber valid. elevated caused chemical changes involving rupture formation primary valence bonds. These changes, responsi...
