Convergent plate margins are arguably the most complicated and dynamic plate boundaries on Earth and have been the subject of many investigations and discussions since the advent of plate tectonic theory. Due to the varied, heterogeneous and complex structure of convergent plate margins, which arises from the multiple geological, physical and chemical processes operating at these zones, and bec...

We derive a hierarchy of plate theories for heterogeneous multilayers from three dimensional nonlinear elasticity by means ?-convergence. allow layers composed different materials whose constitutive assumptions may vary significantly in the small film direction and which also have (small) pre-stress. By computing ?-limits energy regimes scaling pre-stress is non-trivial, we arrive at linearised...

natural vibration analysis of plates represents an important issue in engineering applications. in this paper, a new and simplify method for vibration analysis of circular and rectangular plates is presented. the design of an effective robust controller, which consistently attenuates transverse vibration of the plate caused by an external disturbance force, is given. the dynamics of the plate i...

Abstract This paper deals with functionally graded materials (FGM) as modern in transport vehicles. Basic methods of FGM production and areas their application are presented, well an example modelling plate. Bending freely supported square plates under the influence sinusoidal transverse load was analyzed. The made metal (aluminium) ceramic (alumina) which material characteristics change a func...

Mechanical vibrations induced in flexible structures such as beams and plates have been researched through various optimization functions and control theories to optimize transient response dynamic characteristics. Piezoelectric materials sensors/actuators have been used to reduce and control these vibrations. However, stiffened plate has not been investigated and it is a main and important par...

An advantage of functionally graded materials (FGMs) over laminated composites is that material properties vary continuously in an FGM but are discontinuous across adjoining layers in laminated composites. Furthermore, in an FGM material, properties can be graded in all three directions which is more difficult to achieve in laminated composites. FGMs have been used for structural optimization, ...

This paper briefly reviews recent work on gaseous plume impingement flows. As the major part of this paper, also included are new comprehensive studies on high-speed, collisionless, gaseous, circular jet impinging on a three-dimensional, inclined, diffuse or specular flat plate. Gaskinetic theories are adopted to study the problems, and several crucial geometry-location and velocity-direction r...
