The range of sheet materials used in the vehicle industry is very broad: manufacturers can choose the most suitable materials for a given purpose from a wide selection of materials, and it is also common to use sheets of several types of materials, with different thicknesses and physical and chemical properties, within a structural element.
The applied flow curves of the materials are based on measurements.

Fig. 1 Schematic diagram of the downer mixer [9] In this work, the discrete element method (DEM), which has proven to be a simple and effective tool for simulating granular materials [10-14], is employed to investigate the heat transfer of two particulate materials in such mixers to optimize their interior structure.
DEM Model DEM was first developed for rock mechanics [15, 16], and then for bulk materials at large.
Particulate materials with different size and/or density and temperature are fed at the sides on the top, respectively.
To enhance the mixing and also heat transfer between the two materials, baffles are installed on both sides of the downer in a stagger way.

Introduction During the last decades cable-supported bridges (cable-stayed bridge and suspension bridge) have received much attention because of their ability to overcome long span, with reduced erection costs and improved materials utilization, and more and more cable-supported bridges are in-plan or under construction [1-3].
Consequently, from the deformational characteristics, the more stiffness pylons and reasonable cable parameters, such as the sag-span ratio, cross-section and materials, to reduce the girders’ deflection.
The stay cables’ anchor system and itsequivalent method For hp≤200m and the materials often used today, the curve form equation can be approximated by straight line.

Introduction Many porous materials, such as filter materials made of sintering metals, lagging materials, fireproof materials and so on, are utilized for various fields.
The authors[5],[6] also have dealt with statical problems and dynamical ones of axisymmetrical shells made of porous materials.
Then in this paper the dynamic problems of non-homogeneous (the functionally graded) porous shells of revolution made of such materials are treated.
