Hygro-mechanical Modelling of Wood and Glutin-based Bond Lines of Wooden Cultural Heritage Objects

摘要

A comprehensive modelling of the transient hygro-mechanical behaviour of complex wooden structures by finite element method is targeted. New methods and material models for glutin-based bond lines are developed, since bond lines proved to have significant influence on moisture transport and fracture behaviour. The models are validated and applied to the structural analysis of wooden music instruments exposed to mechanical and hygric loadings.
