The study of road pavement performance through impact hammer tests
International Conference “Environmental Engineering”, 2020 Noise pollution has become an important issue. One of the main sources of noise in residential areas is represented by transportation and by the interaction between tyre and road surface. Several studies illustrate that traffic noise is affected by road properties such as acoustic absorption, surface texture, and mechanical impedance.

Hammer impact test applied for fouling detection in pipelines [PDF]
Sba: Controle & Automação Sociedade Brasileira de Automatica, 2011 The fouling detection in duct systems is a persistent problem and remains a relevant demand for the chemical, oil, food and pharmaceutical industries. The fouling is a deposition process of heavy organic and other dissolved solid materials in the transported fluids or suspensions onto inner wall surfaces in fluid transport systems.

On an Impact Testing Machine of Drop Hammer Type
journal of the Japan Society for Testing Materials, 1961 In order to research on the behaviors of destruction of carbon steel forgings by impact bending, we designed an impact testing machine of drop hammer type. The total height of this testing machine is about 5m. The weights of the used drop hammers are 12.5, 25 and 50kg respectively. The maximum distance from the position of test piece to the drop hammer
