Elastic-plastic material characteristics at different moisture content level
Original language description
The mechanical properties of wood are strongly dependent on moisture content (MC), which affects the mechanical performance of wooden structures or single timber elements subjected to environment changes. This should be taken into account when choosing a material for individual applications. Current assessment options offers more than experimental testing; sophisticated modelling tools such as finite element analysis (FEA) can accurately predict the moistureaffected mechanical behaviour of wooden structures. For this purpose FEA requires the specific material characteristics of wood at different MC levels. The goal of this work is to model the elastic-plastic mechanical behaviour of Oak wood (Quercus L.) at different MC levels. In order to achieve this goal, these partial steps were fulfilled: (a) performing of in-house standard tests (compression, tension, shear and three-point bending) at 20oC and 65% and 100% of relative humidity (RH) environment, (b) collecting of all needed material characteristics and populating of material models for FEA, (c) validation of the material models by confronting of predicted mechanical behaviour with experimental one on a simple wooden object, and (d) calibration of material models by iterative changing of individual material characteristics until the prediction was consistent with a reference.
