摘要
针对具有“老化”特性的粘弹性材料,从不可逆热力学角度给出了其本构关系应该满足的条件;以混凝土材料为例,对某些蠕变关系式进行探讨,指出了老化材料蠕变方程应该满足的关系。
Based on the non-reversible processes, the thermodynamic requirements are presented
on the constitutive equations of visco-elastic materials, showing 'ageing' properties. Further investiga-
tions are carried out onto some of the creep compliance functions of the ageing concrete. The limitations
are also indicated.
