In this paper, thermo-elastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient, internal pressure and external pressure is presented. Given the existence of shear stress in the conical shell due to thickness change along the axial direction, the governing equations are obtained based on first-order shear deformation theory (FSDT). These equations are so...

Linear and arcuate rilles (simple graben) represent some of the most distinctive tectonic features on the Moon. They have been interpreted to be linked to impact basin structure (Mason et al., 1976), and to the emplacement of mare deposits in the basins via flexural deformation related to the mare deposit load (Solomon and Head, 1980). Linear rilles are generally thought to represent deformatio...

We present analog experiments on dike propagation, followed by a numerical model of horizontal and vertical growth, which is partially analytical based empirical observations. Experimental results show that the growth rates are similar until buoyancy becomes significant and, afterward, dominates. The defined for different conditions in homogeneous medium: (a) constant flux, fracture-limited pro...

The original protocol for implant prosthesis recommends the use of a gold framework for acrylic and ceramic prosthesis. However, due to its high cost, the use of alternative alloys is desired. This study compares the marginal accuracy of pre-made cylinders versus plastic cylinders cast with two different base metal casting alloys. Five samples each of (1) plastic cylinder cast in cobalt-chromiu...

In this study, the mechanical behaviours of thick-walled hollow functionally graded material (FGM) cylinder subjected to uniform pressures at inner and outer surfaces are proposed. The FGM has variable geometric profile, thickness properties like elastic modulus mass density all assumed vary radially according exponentially-varying functions in radial direction. With help infinitesimal elastici...

Using the Frobenius series method (FSM), an analytical solution is developed to obtain mechanical stresses of thick spherical pressure vessels made of functionally graded materials (FGMs). The cylinder pressure vessel is subjected to uniform internal pressure. The modulus of elasticity is graded along the radial direction according to power functions of the radial direction. It is assumed that ...
