Load cycles are performed within the elastic regime, up to yielding, and after successive increments of steady ductile flow. At the tested conditions, the samples exhibit ductile behavior with slight work hardening...

To evaluate the possible different impacts of regular and irregular cyclic loading on soil behavior, the irregular (real) urban noises data were converted to regular (modified) data. The result showed that although the total amounts of stress were equal in both regular and irregular data...
