Abstract.
In recent years, the studies by Madenci and his group [3, 4] enlarged to objective of Xiong's analysis, while simplifying his procedure, taking into account also thermal effects; in both cases, the key idea was to define a zone of influence for each fastener, modelled as an elastic beam, and to proceed by superposition, writing a set of equilibrium equation to couple the plate behaviour with the displacements of bolts; a particular characteristic of that analysis, which examined only bolted joints, was that it considered only composite plates, as its main interest was to define the load carried by each lamina, in order to evaluate the corresponding failure conditions.
The first case we dealt with was a 4 mm solid aluminium rivet; as Ls-Dyna axialsymmetric elements aren't suited for such an analysis, especially for what concerns the response of a rigid material, we resolved to carry out the analysis through solid elements; the study was performed studying a quarter-symmetry model (Fig. 1) of the rivet, pinching two as well as three aluminium sheets; the model was composed by 6,526 nodes and 6,272 elements, inclusive of the hammer - modelled as a rigid plate - and of the elements needed to simulate the contact surfaces.
Even if the results show a degree of uneveness that perhaps a finer mesh would prevent, it is clear that for the larger gap there is no heading in the top sheet, which can be ascribed to both the axial riveting load and to the action of the surrounding material.

Abstract: In this paper, we have presented a method to generate efficient NC tool paths based on the surface subdivision.
Introduction Currently, sculptures have a wide range of applications, but the NC machining efficiency of sculptures is very low, there are two primary reasons: the first, the sculptured surfaces are complex, the geometric characters and curvatures of the surface change large, the second, the machining of sculptures belongs to brittle and hard materials machining, the machining mills wear seriously.

Abstract.
As for the hard tissue implants, the bioactivity and the bonding strength between the coating and substrate are the key targets for evaluating the performance, which depends mainly on the composition, structure and preparation process of coatings.
