... to the injection/production of cold/hot water in a doublet. The impact of these cyclical loads on cement has yet to be discovered. Critical state constitutive models such as the Modified cam-clay (MCC) are most suitable to describe cement's mechanical behavior. In this work, we present a new experimental protocol...

... research and laboratory tests on soil behaviour under cyclic loading, especially on clays. The-in situ measurements and tests presented here, which concern the actual behaviour of a clay layer below a North Sea gravity structure, are probably original. reservoir geomechanics Reservoir...

... foundation design, a model for the behaviour of soil under cyclic loading is needed. It is common practice to use only a limited set of laboratory tests, for instance at constant stress or constant strain amplitude, and to extrapolate from these tests to random wave loading conditions, under e.g. a prolonged...
