Non-linearity Identification of Composite Materials by Scalable Impact Modal Testing

Influence of Different Types of Support on Experimentally Determined Damping Values

“…Secondly, the excitation should be reproducible and not inflicted by human errors. Since both requirements are fulfilled by an automated impact hammer, the SAM1 produced by NV-Tech-Design was utilised in these measurements [21,22]. The point of excitation has been placed, as shown in figure 2, in the lower right corner on the back side of the plate.…”

D9.3 Scalable and Automatic Dynamic Excitation of Non-Linear Structures

“…For instance, bolted or screwed structures, or parts made of multiple materials such as automotive brake pads, present friction interfaces among their constructive parts. These interfaces result in non-linear modal excitation/response relationships, which are in violation of the initial EMA assumptions [2].…”
