Design factor of safety for shear

WebJan 3, 2024 · The partial factor values of DA2 are the same as DA1-C2 with the exception of the resistance factor, which is applied to the shear strength at the slice base. The shear strength is the sum of cohesive strength, frictional strength, and suction strength at the base of each slice. The influence of the resistance factor can be seen in Figure 10. WebThe experimental design used to optimize the manufacturing process of high-shear wet granulation was produced using Design-Expert ® software (version 12; Stat-Ease Inc., Minneapolis, MN, USA).
