For the modal and harmonic analysis, their first step was to evaluate the eigenmodes, or the natural vibrations of the system, and determine which ones were relevant to the study. The setup was completed by fixing the impact surface of the hammer and applying a 1g (gravity force = 9.8 m/s/s) excitation in the X-direction, as shown in Figure 21. However, the acceleration gain reported in Figure 22 occurred at different natural frequencies for each of the handle materials.

Examples include: • Unique technologies that improve the recyclability of products and enable recycled content to be incorporated, thus advancing a more circular economy • Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation and reduce carbon footprint • Sustainable infrastructure solutions that increase energy efficiency, renewable energy, natural resource conservation and fiber optic / 5G network accessibility Avient employs approximately 8,700 associates and is certified ACC Responsible Care® and a founding member of the Alliance to End Plastic Waste.
