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.

Contact Stress Distribution

With the rapid development of high-speed machining technology, more and more machining centers have been equipped with the HSK toolholders. In this paper, the performances of the HSK spindle/toolholder interface, such as the axial movement, the radial deflection and the contact stress distribution, were simulated by means of the finite element method and compared with the traditional BT interface. From the simulated results, it was pointed out that the performances of the HSK interface were obviously superior to that of the BT interface, and the HSK interface was much more suitable for high-speed machining.

Loading Scheme

There is no normalized test to assess the shear strength of vertical interfaces of interconnected masonry walls. The approach used to evaluate this strength is normally indirect and often unreliable. The aim of this study is to propose a new test specimen to eliminate this deficiency. The main features of the proposed specimen are failure caused by shear stress on the vertical interface and a small number of units (blocks). The paper presents a numerical analysis based on the finite element method, with the purpose of showing the theoretical performance of the designed specimen, in terms of its geometry, boundary conditions, and loading scheme, and describes an experimental program using the specimen built with full- and third-scale clay blocks. The main conclusions are that the proposed specimen is easy to build and is appropriate to evaluate the shear strength of vertical interfaces of masonry walls.

Coronal Incision

Coronal incision or bitemporal incision is useful for wider visualization in craniofacial surgery. In volume-expanding surgery such as fronto-orbital advancement, however, the incisional scar in the temporal scalp is often undesirably wide and conspicuous. We modified the coronal incision to avoid the widened scar. Further, we analyzed the resulting stress distribution using the finite element method (FEM) to determine whether or not the modification we adapted was effective. The modified method of coronal scalp incision that we used for craniofacial surgery is practical and technically easy. FEM analysis showed that our method was effective in terms of mechanical strength. The simulated surgical craft model is presented and is concluded to be beneficial for further analysis in craniofacial surgery.

Optimizing Design

This paper describes the optimization design of prefabricated XPLE cable accessories and presents the formula of the design of stress cone. The finite element method for optimizing the design of the electric stress distribution inside the HV power cable joint and adjusting the length and curvature of the stress cone of this termination is discussed. The relationships between dimensions of stress cones structure and the electric field distribution were obtained.
