Is the elastic energy of amorphous materials rotationally invariant

摘要: It is shown that scalar, stress induced contributions to the elastic energy, which are not explicitly rotationally invariant can play an important role in determining properties of tenuous structures. Recent scaling results used show scalar tend be dominant at criticality. argued liquid-like hydrostatic stresses large and will lead elasticity many situations as they known do for rubbers.
