Dynamic Stiffness Measurement Data of Building Materials

The dataset contains measurement data for determining the dynamic stiffness of various materials. It includes both raw time series data (force and acceleration signals) and processed results obtained through evaluation algorithms. Measurements were conducted for different material densities and load configurations.
