This research develops thermo-elastic analysis of a functionally graded cylinder under thermo-mechanical loadings. Heat conduction equation in cylindrical coordinate system is solved. Thermal conductivity coefficient is graded along the radial direction. By considering a symmetric distribution of temperature, loading and boundary conditions, strain-displacement and stress-strain relations can b...

Much attention is focused on the relationship between rough sets and many-valued modal logic to deal with approximate reasoning. This paper discusses graded puts forward G(S5). Secondly, by employing operators that correspond operations in G(S5), we introduce concept of upper lower truth degrees a logical formula. Then, propose conditional degrees. Several basic interesting properties are addre...

Rigid pavements are often preferred to flexible types due their higher durability and ease of maintenance also reduce early road failure increase its longevity. This study redesigned a deteriorated segment Oke-Omi pavement as rigid pavement. The thickness was derived using the American Association State Highway Transportation Officials (AASHTO) design method. A programme spreadsheet developed f...

The determination of shear strength characteristics gravelly soils is difficult through the use conventional small scale, triaxial or simple testing devices in laboratory due to membrane compliance and boundary effects; inconsistent penetration resistances measured as part standard cone field. These limitations require available empirical semi-empirical relationships execution large scale field...
