| Popis: |
The Scaling Subtraction Method (SSM) has been proposed in recent years as an effective nonlinear nondestructive technique to evaluate the damage level in concrete and other media and monitor its progression as a function of external actions. Here we show experimental data to prove the robustness of the method with respect to the variation of a number of factors related to either the environmental and testing conditions or the size and geometrical characteristics of the elements tested, as well as to the type of damage and the excitation frequency. An experimentally-derived evolution law is also presented as a first attempt to describe compressive damage progression in concrete in a unified approach. |
