摘要
本文分析了弹性体在可逆过程和不可逆过程中的热力学关系,指出热弹性理论只反映了热传导的不可逆性。当讨论涉及到功转化为热的不可逆性时,则将涉及到拟弹性材料的概念。本文讨论了拟弹性材料的本构关系和热力学关系。
In this paper the thermodynamic relations of elastic body in reversible and irreversible processes are discussed. It has been pointed out that the irreversibility of heat conduction is reflected on only in thermoelasticity. If the irreversibility of converting from work to heat is dealt with, it must lead to build the concept of quasielasticity. The constitutive and thermodynamic relations of quasi-elastic body are considered here as well.
