Response of a Tensegrity Simplex in Experimental Tests of a Modal Hammer at Different Self-Stress Levels

open access: yesApplied Sciences, 2020
The natural frequencies and eigenmodes of the tensegrity simplex are determined experimentally in impact hammer tests. To study an effect of prestressing, the tests are carried out on a physical model 1.2 m high and 0.5 m diameter with build-in ...

Hammer impact test applied for fouling detection in pipelines [PDF]

open access: yesSba: 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]

open access: yes, 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 ...
