Stokes' First Problem, often referred to as the "sudden accelerated plate," was studied using similarity method to obtain velocity and shear stress profile by analyzing the flow of an infinite body of fluid near a wall that experiences sudden motion. The flow is assumed to be Newtonian, viscous, and incompressible, while at initial condition the velocity considered as zero and the condition of the flow were at rest. The obtained results are then numerically solved employing Simpson's approximation. Furthermore, this study explores variations in velocity and shear stress at the wall across different time intervals. The study of the velocity profile within this scenario demonstrates its consistency with the non-slip condition and the specified boundary conditions. Specifically, for t > 0, the velocity of the flow at the surface (y = 0) aligns with the plate's speed, while at y = ∞, the velocity decreases to zero, mirroring the initial condition. The findings reveal that at the moment the plate initiates its motion (t = 0), the shear stress reaches its maximum value. As time progresses, the shear stress at the wall gradually decreases.

“…The statistical properties of the maximum likelihood estimators of the model parameters such as existence, uniqueness and invariance are studied. The mean squared errors of the maximum likelihood estimators are calculated to evaluate their performances through a Monte Carlo simulation study [10]. A statistical-analysis method for accelerated life testing with incomplete data and competing failure modes was proposed.…”

As one of the key components of marine reducer, the life reliability of gear is of great significance to the safe operation of the reducer and even the whole transmission system. However, due to economic and testing constraints, executing extensive fatigue life tests on complex and costly gears presents a formidable challenge, resulting in inadequate reliability assessments. In this paper, the gear life reliability analysis method based on the accelerated life test is proposed. By conducting the gear bending fatigue accelerated life test, the life distribution and failure mechanism are determined based on the accelerated life data. Furthermore, the gear life distribution parameters and acceleration model are solved by least squared method. This allows us to derive a reliability index specific to the service conditions, facilitating the evaluation of gear life reliability. The method proposed in this paper provides data and theoretical support for the accelerated life tests, lays a foundation for the gear reliability evaluation under small samples, and improves the efficiency of the gear fatigue life evaluation. It has significant engineering significance in saving test costs, reducing test times and shortening development cycle.
