Pendulum-based rebound resilience measurement is a well-established method for characterizing the energy absorption of elastomers. However, existing standards are limited to elastomers with a hardness range of Shore A30 to A85 and polymeric foams, providing only a single value of rebound resilience without further investigations into material behavior during impact. This study extends the application of this method to a broader hardness range (Shore 00–30 to D50) and enhances the analysis with advanced instrumentation, including a piezoelectric load cell, an angular transducer, and a high-speed camera, which enables capturing the impact duration, impact force, specimen compression, and the determining of elastic energy during the impact.
