Frequency sweep rate and amplitude influence on nonlinear acoustic measurements
2006 (English)Conference paper, Published paper (Refereed) PublishedAlternative title
Frekvenssvephastighet och amplitud-påverkan på olinjära akusiska mätningar (Swedish)
Abstract [en]

When subjecting a solid material to acoustic excitation with varying amplitude and sweep rate, the frequency shift response is not always behaving linear with amplitude. This phenomenon is connected to intricate nonlinear mechanics appearing in naturally imperfect materials and in damaged non-atomic solids. It is being investigated for different excitation amplitudes and for varying frequency sweep rates. This onset distribution can be mapped as an activation density.
