Tomorrow, June 24, 2022, the free CULTWOOD user workshop in Dresden will dealwith hygro-mechanical finite element analyses of historical wooden objects under mechanical and climatic stressfor damage risk assessment – a project of the Institute for Statics and Dynamics of Structures (ISD) of the TU Dresden in cooperation with the Dresden University of Fine Arts (HfBK) and the Dresden State Art Collections (SKD). Registrations are still being accepted!
Preventive conservation measures as well as conservation and restoration interventions are carried out in museum collections as well as in heritage conservation practice according to the available possibilities and requirements based on the current state of knowledge and personal experience. Time and again, conservators come across situations in which objects are exposed to changing climatic and mechanical influences, the consequences of which can only be vaguely assessed. Examples of this are situations in loan traffic, unsuitable storage conditions or new presentations of objects. One way of estimating the long-term risk of damage to wooden objects caused by mechanical or hygromechanical influences is to model and simulate the objects in various climate scenarios using the finite element method.
As part of the CULTWOOD1 research project at the Institute for Statics and Dynamics of Structures (ISD) at the Technical University of Dresden in cooperation with the Dresden University of Fine Arts (HfBK) and the Dresden State Art Collections (SKD), complex hygro-mechanical material models for wood and coatings are being developed, simulations carried out and validated. The numerical modeling of cultural objects made of wood has been successfully researched, further developed and applied at the ITS for several years. For example, as part of the research project “VIRTEX – Virtual Experiments for Wooden Artwork “2 Russian icons were examined and simulated and the status of numerical simulation of wooden cultural objects was discussed internationally.
The main focus of the project includes art technological and joining studies of the selected models as a basis for the best possible faithful reproduction of the replicas to be simulated. While the art and joining technology findings on the cabinet are based on practical investigations, the Cranach panel is based on previous SKD documentation (Marx 1996) on the object as well as on the general state of knowledge on the art technology of the Cranach workshop (Heydenreich 2007). While the material models for the replicas were being developed, extensive preliminary tests were carried out to determine their specifications. These preliminary tests include experiments to determine parameters for material properties, pure validation experiments to investigate the interaction behavior of different materials, and experiments that serve both to determine parameters and to validate them. These small-scale experiments are carried out in close cooperation with the Institute of Wood Technology Dresden (IHD). Finally, the simulation results of the replicas are compared with the measurement results of the practical experiments.
