in this paper, an analytical solution for computing the linear plastic stresses and critical temperature and pressure in a fgm hollow cylinder under the internal pressure and temperature is developed. it has been assumed that the modulus of elasticity and thermal coefficient of expansion were varying through thickness of the fgm material according to a power law relationship. the poisson's...

energy crisis, global warming and other environmental issues are what motivate researchers to find new strategies to reduce energy consumption in buildings. recently, using phase change materials (pcm) in the building’s envelopes has drawn significant attention as an energy-saving method, which helps in increasing the building’s thermal capacity. in the present research, the effects of the main...

Seafloor temperatures measured during the SAX99 experiment off Fort Walton Beach, Florida, included sharp decreases in response to the passage of cold fronts. Sediment pore water temperatures exhibited an increasing temperature (3-4o Cm) with depth in the sediment. By fitting a heat conduction model to the gradient data, the thermal diffusivity of the sediment was estimated to be 0.006 cms. The...

changing altimetry information from satellites on the surface of seas and oceans, into anomaly gravity for example free air anomaly, is a fundamentally new method presented by researches. the determination of the free air gravity anomaly over the earth’s marine regions has led to a major improvement in our understanding of plate tectonic processes relating to oceanic ridges, the formation of ma...
