Czwarty wykład trzeciej edycji HS Academy zostanie wygłoszony w czwartek, 24 kwietnia o godz. 15:00 przez doktor Laurę Brambilla i nosi tytuł
“Acoustic emissions techniques applied to historical vehicle engines”
Wykład ten stanowić będzie wprowadzenie do technik emisji akustycznej stosowanych w nauce o dziedzictwie. Emisja akustyczna to nieinwazyjna, nieniszcząca technika (NDT), która jest stosowana w przemyśle od lat 50. XX wieku, a także w dziedzinie badań dziedzictwa kulturowego od połowy lat 90. XX wieku. W tym zakresie stosowana głównie do monitorowania pęknięć wewnątrz różnych typów obiektów (przedmiotów drewnianych, obiektów metalowych, emalii, zabytków budowlanych, rzeźb, obrazów) ze względu na zmiany warunków środowiskowych oraz do zintegrowanego zwalczania szkodników, umożliwiając wykrywanie aktywności owadów wewnątrz drewna.
Technika emisji akustycznej, szczególnie w zastosowaniu do obiektów drewnianych, znajduje się również w naszej ofercie, p. Emisja akustyczna.

For the 3rd edition of the Current Topics in Heritage Science lecture series, organized by the emerging professionals of the E-RIHS HS Academy, the fourth lecture will be delivered on April 24th, 2025, at 3 pm (CEST), by Laura Brambilla. The lecture “Acoustic emissions techniques applied to historical vehicle engines” will provide the attendees with an introduction on acoustic emissions techniques applied to heritage science.
Speaker:
Laura Brambilla head of studies and research of HE-Arc CR, got her PhD in chemical sciences from the Università degli Studi di Milano, Italy. She joined the Ra&D team of Haute Ecole Arc conservation-restoration in Neuchâtel, Switzerland, in April 2013 and she became professor in 2017. She has been leading several research projects: CANS (Conservation of cAns in collectioNS), an interdisciplinary research funded by SNSF dedicated to the conservation of food cans in museums and collections; ACUME_HV project, using Acoustic Emission methods for monitoring historical vehicles; FLUIDIS and LIQUOR projects, dedicated to natural history collections in fluid. She is currently project leader of the CORINT project, a SNSF Sinergia research dedicated to the investigation of iron artifacts in opaque porous media using multimodal imaging techniques (neutrons and X-rays).
Abstract
Acoustic emission is a non-invasive, non-destructive technique, belonging to the NDT class (non-destructive testing), that is used in industry since the 1950s and applied also to the field of cultural heritage since the mid-1990s. It is based on the principle of elastic waves propagation in a material when a sudden release of energy inside the material itself occurs. This release of energy may happen due to a wide range of events taking place inside a solid material, such as the formation of a crack, corrosion phenomena, friction between two surfaces… The energy waves generated by the event travel inside the material and can be captured by piezoelectric sensors placed on the surface of the object. Acoustic emission allows then the detection and monitoring of a series of phenomena. In the field of cultural heritage, it is mainly applied to monitoring of cracks inside different types of objects (wooden objects, metal objects, enamels, built heritage, sculptures, paintings ….) due to environmental conditions changes and to integrated pest management, allowing to detect the activities of insects inside wood. In the field of automotive industry, acoustic emission is used to monitor the performances of newly produced engines. In the ACUME_HV project (Acoustic Emission Monitoring of Historical Vehicles) we have applied Acoustic Emission to historical vehicles’ engines in order to perform a diagnosis of the state of conservation of the mechanical parts of the engines, due to wear, friction or corrosion, before their reactivation. During the talk you will learn about the Acoustic Emission techniques and their application to the diagnostic and monitoring of historical engines.
Key topics
- Basic knowledges on Acoustic Emission
- Experimental set-up
- Diagnostic and monitoring through data treatment
You will learn
- Use of Acoustic Emission for the monitoring of cultural heritage, focusing on the example of historical vehicles
- Importance of the correct set-up of the experiments; materials and parameters
- Perform diagnostic and monitoring of the state of conservation of the engines: role of wear, friction and corrosion
