SUMMARY
It is expected that the total dissipated energy per unit volume will increase at a decreasing rate.
Monitoring of the accelerations and the displacements at different depths permits the reconstruction of the shear stress-strain time histories and consequently, the energy per unit volume at any instant up to liquefaction.
By comparing the calculated unit energy from the time series of a design earthquake with the resistance to liquefaction in terms of energy, it can be decided whether or not liquefaction is imminent.
