The built up layer thickness in secondary deformation zone is one of the important parameters in metal cutting process. The built up layer (BUL) is formed in second deformation zone near the tool-chip interface in the back of the chip. This parameter influences the tool life and machined surface quality. This BUL should not be confused with the built up edge (BUE). The deformation of the BUL in...

International trade specialisation reflects differences in relative factor productivity and endowments, economies of scale or specific advantages of firms and it can have a significant impact on economic growth. We focus in this paper on trade specialisation dynamics in two Eastern European countries (Romania and Bulgaria – EEC-2) vis-à-vis the EU member states (EU-25). Specifically, we are int...

Interest in the seakeeping loads of vessels has increased dramatically in recent years. In current design practice, methods for predicting seakeeping motions and loads are mainly in two categories, strip theory methods and 3Dpanel methods. Methods based on strip theory provide reasonable motion prediction and are computationally efficient. However, many strip theory methods provide only hull gi...

We presented the surface accuracy measurements of 5 single panels of the Shanghai 65-meter radio telescope by employing the coordinate measuring machine and laser tracker. The measurement data obtained from the two instruments were analyzed with the common point transformation and CAD surface fitting techniques, respectively. The derived rms uncertainties of panel accuracy from two methods are ...

Investigating the behavior of the box-shaped column panel zone has been one of the major concerns of scientists in the field.  In the American Institute of Steel Construction the shear capacity of I-shaped cross- sections with low column thickness is calculated. This paper determines the shear capacity of panel zone in steel columns with box-shaped cross-sections by using artificial neural netw...

This paper suggests the use of a plywood panel, which is also a scenographic element in a dance performance, as a flat speaker. The sound emanating from the panel is subjectively different from a traditional loudspeaker, since the sound appears to originate from behind the panel. However, its frequency response is severely coloured by the panel modes, and the panel has a displeasing low pass-fi...

In this contribution, the variational problem for Kirchhoff plate based on modified strain gradient theory (MSGT) is derived, and Euler-Lagrange equations governing equation of motion are obtained. The Galerkin-type weak form, upon which finite element method constructed, derived from problem. shape functions satisfy homogeneous partial differential as extensions Adini-Clough-Melosh (ACM) Bogne...

The study considers a method for forming stiffened monolithic panels by local deformation of the panel ribs. is caused bending moments along rib towards each other. goal to numerically model process utilizing designed local-impact tool and analyze its effects on panel, obtaining which experimentally challenging. finite element (FEM) modeling performed in ANSYS validated experimental made an alu...
