Detailed explanation-1: -Plastic flow is associated with the presence of flocculated particles in concentrated suspensions. As a result, a continuous structure is set up throughout the system.
Detailed explanation-2: -The first equation may be replaced by the plastic flow rule Y p = n + 1 p − n p − n ¯ n + 1 ¯ n + 1 = O . Then, the stress is calculated by substituting n + 1 e = n + 1 trial − n + 1 p into the hyperelastic equation.
Detailed explanation-3: -Introduction. Many complex fluids, such as network forming polymers, surfactant mesophases, emulsions etc do not flow until the applied stress exceeds a certain critical value, known as the yield stress. Materials exhibiting this behavior are said to be exhibiting yield flow behavior.
