The paper presents experimental works related to contact nonlinearities. The research is focused on effects derived from hysteresis stiffness characteristics and vibro-impacts generated during the relative movement of two surfaces. The modeling of th

Numerous nondestructive testing (NDT) methods have been developed to perform inspections of engineered structures. Frequently, increased precision of a given method is associated with longer inspection time. The trade-off between precision and inspec

Wrinkles in carbon-fiber reinforced plastics (CFRP) are extremely dangerous, dramatically changing the performance of a composite structure. However, wrinkles are one of the most difficult defects to detect and characterize with ultrasound since they

The paper presents experimental investigation of sidebands in vibro-acoustic modulation test, generated as an effect of contact-type nonlinearity. The two samples with prepared contact surfaces were tested in experimental works. Two excitation types:
