Seismic soil liquefaction is a recurring phenomenon that may cause significant damage to infrastructure during earthquakes and that in turn may also cause injuries and even fatalities. This phenomenon has been widely studied by researchers, and for its study the laboratory characterization of behavior of sands when subjected to cyclic loading is very important. One of the approaches for this kind of studies is through the calculation of the energy that is dissipated by the soil when it is subjected to cyclic loading. One of the hypotheses for utilizing these energy methods states that the cumulative dissipated energy required in a soil to reach failure only depends on the initial state of the sample (relative density and initial vertical effective stress) and should be reasonably constant and independent of the loading amplitude and waveform applied to the sample.
