液体粘度の温度・静水圧依存性 : 非弾性構成式に関する研究

抄録

The constitutive relation between viscosity, temperature and hydrostatic pressure of liquid materials is investigated by the inelastic deformation theory (combined mechanism model) proposed in the previous paper in order to explain the inelastic behavior of solid materials. The constitutive relation of water and some other liquid materials is well-explained quantitatively by the theory. The following are obtained : liquid flow due to several mechanisms, which are the thermal activation processes similar to those of solid materials ; the liquid region in a pressure-temperature diagram is divided into several (mainly three) subregions classified by flow mechanism ; a proposed constitutive equation containing hydrostatic pressure.
