... limitations, considering the concepts of soil mechanics. In this paper, a framework to model the MSW mechanical behaviour is proposed, based on results from laboratory tests, such as triaxial compression and confined compression on large samples. It is admitted that the MSW mechanical behaviour is commanded...

... This research was performed on coupled effects between mechanical behaviour and mass transfer properties of salt. The work was carried out in support of the long term safety analysis of underground storage facilities in salt, especially radioactive waste repositories. It consists of three parts...

Many samples were tested at a wide range of water contents varying from oven-dried to saturated condition. A general equation was developed...

... of strain rate on mechanical behaviour of some Indian rocks. A third degree polynomial has been found to give the best fit to the plot between ultimate strength and strain rate, and Young's modulus and strain rate of rock samples. The failure strength was found to increase with increase in strain rate...
