EXPRESS-G is a graphical modeling notation developed within STEP and used for IFC definition. It is used to identify classes, the data attributes of classes and the relationships that exist between classes. EXPRESS-G is directly related to the EXPRESS data definition language. That is, everything that is drawn in EXPRESS-G can be defined in EXPRESS. However, not everything that can be defined i...

In The Foundations of Mathematics in the Theory of Sets, John Mayberry attacks the 2000-year-old problem of accounting for the foundations of mathematics. His account comes in three interrelated parts: determining exactly what one should (and should not) expect from a foundation; arguing that set theory can in fact provide such a foundation, and presenting a novel version of set theory (or at l...

In this paper, buckling behavior of moderately thick functionally graded rectangular plates resting on elastic foundation subjected to linearly varying in-plane loading is investigated. The neutral surface position for a functionally graded plate which its material properties vary in the thickness direction is determined. Based on the first-order shear deformation plate theory and the neutral s...

In prior literature, it has been generally seen that there is no explicit theory of project management. We contend that it is possible to precisely point out the underlying theoretical foundation of project management as espoused in the PMBOK Guide by PMI and mostly applied in practice. This foundation can be divided into a theory of project and a theory of management. We link theories to the b...

This article provides a fully analytical approach for nonlinear equilibrium path of rectangular sandwich plates. The core of structure is made of symmetric cross-ply laminated composite and the outer surfaces are piezoelectric actuators which perfectly bonded to inner core. The structure is subjected to electro-thermo-mechanical loads simultaneously. One side of plate is rested on Pasternak typ...

In this paper, static and free vibrations behaviors of the orthotropic functionally graded material (FGM) plates resting on the two-parameter elastic foundation are analyzed by the a mesh-free method based on the first order shear deformation plate theory (FSDT). The mesh-free method is based on moving least squares (MLS) shape functions and essential boundary conditions are imposed by transfer...
