Abstract

Triangulation laser displacement sensors have allowed for precise in situ measurements of short-, medium-, and long-term dimensional responses of sculpted wooden elements to variations of temperature and relative humidity. They show that massive wooden elements are endangered by mechanical damage. Most numerical modeling of the phenomenon quantified gradients of moisture contents and related stress distributions for a cylindrical object, imitating a wooden sculpture, subjected to a range of microclimatic fluctuations reflecting real-world situations. The obtained stress levels permit the determination of allowable thresholds in the magnitude and rate of the air parameter fluctuations which the wooden objects may ultimately endure without irreversible deformation or damage.
