The contributions at hand contain, first, models for the transient structural analysis of wooden artwork at hygro-mechanical long-term loading. Second, a multi-physical constitutive model for wood at finite deformations is developed and applied to a non-linear finite-element approach to model the temperature and moisture dependent densification of wood. Third, the influence of friction between the surfaces of spruce wood and steel alignments on the material properties assessed through a three-point bending test is examined utilizing an anisotropic constitutive model and a displacement-driven approach for rigid-deformable contact subdomain.

摘要

The contributions at hand contain, first, models for the transient structural analysis of wooden artwork at hygro-mechanical long-term loading. Second, a multi-physical constitutive model for wood at finite deformations is developed and applied to a non-linear finite-element approach to model the temperature and moisture dependent densification of wood. Third, the influence of friction between the surfaces of spruce wood and steel alignments on the material properties assessed through a three-point bending test is examined utilizing an anisotropic constitutive model and a displacement-driven approach for rigid-deformable contact subdomain.
