To apply the theory of meniscus instability to polymers and glassy metals, theoretical and experimental analyses of the flow with free surface were conducted. In this study, the relation between the modified capillary number and the minimum wavelength of disturbance was derived by the minimum principle of viscous dissipation energy. The relation was compared with the experimental results which were obtained by using glycerine and silicone oils of various viscosities. Agreement of the theoretical relation with the same experimental one was very good. The energy requirements for moving plates with respect to each other were experimentally given under various experimental conditions. The energy could be arranged by using the modified capillary number. Maximum load during plate movement was also investigated. Finally, the equation for calculating the energy from the minimum wavelength could be obtained in this study.
