ItemIn-situ, non-invasive investigation of an outdoor wooden sculpture(International Council of Museums, 2014-09-14)This paper reports on the development of a radio- frequency sensor unit for the non-invasive monitoring of Bruce Armstrong’s outdoor wooden sculpture constructed from River Red gum (Eucalyptus camaldulensis). This technique collects realtime data in situ in outdoor environments. Sensor units employing electromagnetic radiation in the microwave to radio frequency part of the spectrum can detect moisture changes, mould growth and termite infestation in specimen Australian timbers used in works of art. Model experiments using wood samples showed that moisture changes,decay levels, invasion of wood by insects such as termites and wood deterioration due to fungal attack can be detected with both ‘look through’ and radar-based microwave sensors. The monitoring provided information on the time response, temporal and cyclic activity of an outdoor, exposed wooden sculpture to moisture. A radio-frequency sensor is applicable for the monitoring of cultural materials to inform damage functions and dose values.

ItemNo Preview AvailableQuality assessment of Eucalyptus delegatensis dried in the solar kiln(IUFR, 2017)This research aimed to assess the timber quality of Alpine Ash known as Eucalyptus delegatensis dried in a solar kiln. The maximal temperature and relative humidity (RH) during daytime were set at 430C/72% RH and during the night time at ambient temperature (AmbT)/90% RH. The results showed that the humidity was not reached but all sample boards were under the acceptable limit of cupping, spring, and bow. However, the twist of three out of twelve sample boards was above the acceptable limit. The mean compressive strain was -2 x 10-4 mm/mm in the core layers and the tensile strain was 14 x 10-4 mm/mm in the outer layers. Mean moisture gradient was 0.6% MC between outer and inner layers. There was a significant difference in moisture content at end section compared to the front and middle sections. Internal checking, collapse, stress residual were graded as “C” based on Australian standard AS/NZS 4787:2001.
