.... Introduction A Newtonian fluid is a fluid in which the shear stress is directly proportional to the shear rate. A non-Newtonian fluid is a fluid in which such proportionality does not exist (Figure 1). For instance, in a yield stress fluid, there is a threshold shear stress called yield stress. As the shear...

... stress can be calculated at different given normal stress, generating a series of shear stress and normal stress, and the values of cohesion and friction were determined via linear regression analysis. Then take the research on shear strength of rock mass from China-Myanmar Oil and Gas Pipelines...
