Model Predictions

A practical explicit 3D finite element analysis model has been developed and implemented to analyze turning hardened AISI 52100 steels using a PCBN cutting tool. The finite element analysis incorporated the thermo-elastic-plastic properties of the work material in machining. An improved friction model has been proposed to characterize tool-chip interaction with the friction coefficient and shear flow stresses determined by force calibration and material tests, respectively. A geometric model has been established to simulate a 3D turning. FEA Model predictions have reasonable accuracy for chip geometry, forces, residual stresses, and cutting temperatures. FEA model sensitivity analysis indicates that the prediction is consistent using a suitable magnitude of material failure strain for chip separation, the simulation gives reasonable results using the experimentally determined material properties, the proposed friction model is valid and the sticking region on the tool-chip interface is a dominant factor of model predictions.

Mesh generation plays an important role in determining the result quality of finite element modeling and structural analysis. Building information modeling provides the geometry and semantic information of a building, which can be utilized to support an efficient mesh generation. In this paper, a method based on BRep entity transformation is proposed to realize the finite element analysis using the geometric model in the IFC standard. The h-p version of the finite element analysis method can effectively deal with the refined expression of the model of bending complex components. By meshing the connection model, it is suggested to adopt the method of scanning to generate hexahedron, which improves the geometric adaptability of the mesh model and the quality and efficiency of mesh generation. Based on the extension and expression of IFC information, the effective finite element structure information is extracted and extended into the IFC standard mode. The information is analyzed, and finally the visualization of finite element analysis in the building model can be realized.

The Impact

In the past finite element analysis (FEA) and multi-body system simulation (MBS) were two isolated methods in the field of mechanical system simulation. Both of them had their specific fields of application. In recent years, it is urgent to combine these two methods as the flexible multi-body system grows up. This paper mainly focuses on modeling of the spindle system of hammer crusher, including geometric model, finite element model and multi-body dynamics (MBD) model. For multi-body dynamics modeling, the contact force between hammer and scrap steel was discussed, which is important to obtain the impact force. This paper also proposed how to combine FEA and MBS to analyze the dynamic performance of the spindle system by using different software products of MSC.Software.

A simple yet efficient paradigm for geometric mesh generation using the Visible Human Project Male dataset for further finite element analysis was presented. The minimum distance classifier was used for the discriminant function between the class centers classified by the fuzzy c-means clustering method in the RGB space. Furthermore, based on two major geometric assumptions on the boundary curves, star-shaped polygon and geometric conformity, a points-on-line search technique was devised for efficient computation of the boundary points of the contours for each anatomical component of the human forearm complex. The computed boundary points in each slice were fitted to a closed spline curve and resampled and then refitted for correct alignment with the consecutive boundary curves in order to improve geometric fidelity. By using the refitted contours, a 3-D geometric model of the human radius, ulna, and surrounding soft tissue was generated in a commercial computer–aided design system and exported to a commercial finite element analysis package for meshing with its built-in automatic mesh generator. The proposed method can be applied to geometric mesh generation of other long bones, which allows easy handling, storage, and exchange of the model.

This paper discusses the influence of asymmetrically damaged ships on the ultimate hull girder strength. When such damages take place at the asymmetric location of cross sections, not only translation but also inclination of instantaneous neutral axis takes place during the process of the progressive collapse. To investigate this effect, the Finite Element Analysis (FEA) is employed and the damage is assumed in the middle hold. The collision damage is modeled by removing the plate and stiffener elements at the damage region assuming the complete loss of the capacity at the damage part. For the validation results obtained by Finite Element Analysis of the asymmetrically damaged ship hull girder, the simplified method is adopted. The Finite Element method of ultimate strength analysis of a damaged hull girder can be a practical tool for the ship hull girder after damages, which has become one of the functional requirements in IMO Goal Based Ship Construction Standard.
