The transient flow in the sector region bounded by two intersecting planes and a circular cylinder is determined in the Stokes approximation. The plane boundaries are assumed to be at rest while the cylinder is rotating with a constant velocity starting at t = 0. The problem is solved by means of three different methods, a finite element, a finite difference, and a boundary element method. The corresponding problem in which the constant velocity boundary condition on the cylinder is replaced by a condition of constant stress is also solved by means of the finite element method.

Concentration Phenomenon

Focus on stress concentration and high stress area, four improvements were put forward through analyzed a hydraulic excavator's boom with the finite element method under the bucket digging condition. Compared the stress distribution graph, the results show that these schemes can improve the stress concentration phenomenon and the high stress distribution areas. The practices demonstrated the effectiveness to reduce the invalidation rate of hydraulic excavator's boom.

Loosening of cemented hip prostheses has been reported on occasion. Although a few laboratory experiments have replicated clinical failure modes, the methods appear to be very complicated and time consuming. In this analysis, the Finite Element Method was utilized to evaluate the stress distribution in a cement layer. Two distinct hip implant designs with and without grooves in the anterior/posterior surfaces were investigated. The results indicate that the features of the multiple grooves in these cemented hip implants may improve the rotational stability and reduce the cement stress at the implant-cement interface.
