THE MECHANICAL MODEL OF OBLATE SHELL FOR COBWEB FISSURE OF OCEAN FLOOR SPREADING
Fan Jiashen Shu Chen(Yunnan Institute of Technology, Kunming)
Consider the oceanic plate with radius in order of magnitude 103 km such as the Pacific Plate, the curvature of the Earth must be taken into consideration. Therefore, we take it as a thin shallow spherical shell on elastic foundation accompanying with thermal effect of radiogenic heat within the litho-sphere and the influence of pressure by melting temperature together with eccentric loading exerted by oceanic water on the surface of the Pacific Plate. We obtain not only the exact analytical solutions but also the asymptotic analytical solutions, for the later is more convenient in practical use.
