Effect of Hammer Type on Generated Mechanical Signals in Impact-Echo Testing [PDF]
Materials, 2021 The impact-echo diagnostic method is a well-known nondestructive pulse compression test method, which can be relatively easily used for the testing of concrete and reinforced concrete elements. The evaluation of the measurement with this method is based on the analysis of the signal itself in the time and frequency domains.

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.

LLNL small-scale drop-hammer impact sensitivity test [PDF]
, 1995 Small-scale safety testing of explosives and other energetic materials is done to determine their sensitivity to various stimuli including friction, static spark, and impact. This testing is typically done to discover potential handling problems for either newly synthesized materials of unknown behavior or materials that have been stored for long ...
