چکیده
Loss of stress support caused by hydrate dissociation may result in a significant reduction of rock strength. The strength of a hydrate-bearing sedimentary formation is a function of the strengths of inter-granular bonds and the interactions between the rock grains and the hydrates in the pore space. Myriads of such bonds and interactions define the macroscopic rock strength parameters. We expect that the history or hydrate formation has a great impact on the character of hydrate distribution and, consequently, on the possible scenarios of failure of a hydrate-bearing rock.

متن کاملDevelopment of a mathematical model to design an offshore wind and wave hybrid energy system
Fossil Fuels are always considered as environmental pollutants. On the other hand, the political and economic situations highly affect the price of these fuels. Offshore wind and wave, as renewable energy sources, represent the better alternatives for electricity generation. Therefore, it is necessary that wind speeds effectively be estimated due to the absence of field measurements of the wind...
متن کاملGeomechanical Constitutive Modelling of Gas-hydrate- Bearing Sediments
In this work and in order to consider theoretically the effect of gas hydrates on the mechanical properties of their host sediments, hydrate fraction was introduced as a state variable in the framework of a Critical State model. For the proposed model, the process of de-structuration and softening of natural clay was considered as a proxy for the gas-hydrate-bearing-sediments behaviour. The dev...
متن کاملSystem identification of a beam with frictional contact
The nonlinear system becomes an area with numerous investigations over the past decades. The conventional modal analysis could not be applied on nonlinear continuous system which makes it impossible to construct the reduced order models and obtain system response based on limited number of measurement points. Nonlinear normal modes provide a useful tool for extending modal analysis to nonlinea...
متن کاملThe Effect of Chemical Composition on Wear and Microstructural Properties of Babbitt Coatings
Babbitt is a white silvery alloy that composed of Tin, Lead, Copper and Antimony. This alloy is the most current bearing alloy in industrial applications. The characteristics of this alloy, such as high wearing resistance and low coefficient of friction, have converted it into a bearing cover. The target of this study is investigation on the effects of alloy elements on wearing and micro-struct...
