Abstract The article presents influence of modification of the low-alloy cast steel G17CrMo5-5 by rare earth metals on stress distribution in front of the crack at the initial moment of the crack extension. Experimental studies include determination of strength and fracture toughness characteristics for unmodified (UM) and modified (M) cast steel. In the numerical computations, experimentally tested specimens SEN(B) were modelled. The true stress–strain curves for the UM and M cast steel are used in the calculation. The stress distributions in front of the crack were calculated at the initial moment of the crack extension. On the basis of data on the particle size inclusions in the UM and M cast steel, and the calculated stress distributions was performed an assessment of the possibility of the occurrence of cleavage fracture. The analysis results indicate that at room temperature for the UM cast steel, there is a possibility of cleavage fracture, while for the M cast steel occurrence of cleavage fracture is negligible.

Crankshaft in truck mounted petroleum compressor is constrained by space concerns, design is difficult. In this paper, primary structure design parameters are extracted from the crankshaft design process, and crankshaft stress distribution is calculated under ANSYS, providing a reference for compressor optimization. It is useful to guide the design.

Machining induced residual stress is influenced by many factors. Extensive studies on the influence of cutting parameters, tool parameters, as well as basic properties of materials have been carried out during the past decades, while another important factor, initial stress distribution in workpiece, was often ignored. In this paper a relatively complete FEM simulation on the formation mechanism of machining induced residual stress in high speed machining is carried out, illustrating the three stress zones affected by mechanical and thermal loads, and their influence on ultimate residual stress. And the influence of initial compressive stress on stress formation and cutting forces is analyzed. Initial compressive stress weakens the tensile effect caused by the shear deformation, and the residual stress tend to be more compressive with larger initial compressive stress. Cutting force becomes larger with the increase of initial compressive stress. And the results in this FEM study can be used to explain some unaccounted experimental phenomena in former researches.

The aim of this work is the modeling of the stress distribution in cortical and trabecular bone of model frontal part of mandible by FEM analysis using linear static methods applying monocortical and bicortical fixation of dental implant. Depending on the position of the screw thread with regard to the bone surface, three different cases were simulated: exactly on the bone surface, 1,5 mm above and 0,5 mm below the surface of the cortical bone. It was found out that the stress field in the cortical part and the implant are considerably lower in the case of slightly recessed position in contrast with the above and normal position of the implant in both, monocortical and bicortical fixations. However, bicortical fixation in this case generates slightly lower stress field in the bone and implant parts than in monocortical fixation. Monocortical fixation is otherwise slightly more favorable from the viewpoint of maximum stresses in the bone in the case of exact and above positions of the implant.

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.
