The shear stress in capillary flow of polymer melts at the wall is discussed. The theoretical result suggests that Bagley's formula holds even if the exit pressure is not negligible in capillary flow of polymer melts. The importance is emphasized of distinguishing the pressure in tne axial direct...
Read on to learn more about its formula, units, types and its comparison withpressure. Stress Stress can be defined as the restoring force per unit area within the material that is caused due to externally applied forces. Whenever force or energy is applied to any object it undergoes some ch...
(1) Kolmogorov's theory[1] suggests that two scalars suffice; they are usually taken to be the turbulent kinetic energy K and the dissipation rate ε. The simplest case of Eq. (1) is the eddy viscosity formula $$au = - \\frac{2}{3}KI + {v_T}S$$ (2) where the strain rate ...
(2001) studied the effects of initial normal stress (σn0) and bolt types on the interface shear behavior under a 8.5 kN/mm normal stiffness. Yokota et al. (2018) studied crack propagation mechanism accompanied by debonding process of the bolt-grout interface with various rib parameters and ...
