Measuring stress levels of archaeological samples from the Oseberg ship under fluctuating relative humidity : - preliminary results.

Dionisi-Vici, Paolo ; Braovac, Susan ; Hauer, David and Jensen, Maria LU (2016) p.333-337
Abstract
Long-term effects of climate fluctuations are very important to consider regarding preservation of archaeological wooden artifacts. Since 2009, a hygromechanical monitoring has been carried out on the Oseberg ship in the Viking Ship Museum(VSH) in Oslo. The monitoring has showed a measurable warping response of the oak planks to the uncontrolled relative humidity fluctuations in the museum. However, one of the missing pieces of formation for an improved understanding of the hygro-mechanical behavior of the ship is the measurement of the stress levels potentially absorbed by the restrained planks during relative humidity (RH) fluctuations. Here, a methodology aiming to contribute to this analysis is proposed and the first results of the... (More)
Long-term effects of climate fluctuations are very important to consider regarding preservation of archaeological wooden artifacts. Since 2009, a hygromechanical monitoring has been carried out on the Oseberg ship in the Viking Ship Museum(VSH) in Oslo. The monitoring has showed a measurable warping response of the oak planks to the uncontrolled relative humidity fluctuations in the museum. However, one of the missing pieces of formation for an improved understanding of the hygro-mechanical behavior of the ship is the measurement of the stress levels potentially absorbed by the restrained planks during relative humidity (RH) fluctuations. Here, a methodology aiming to contribute to this analysis is proposed and the first results of the tests are presented. Measurements were carried out in a climate chamber, simulating the average extremes in RH commonly measured at VSH (30% and 75% RH). The experimental results will allow us to determine realistic climatic set points for the plans of a new museum complex. (Less)
