Wood is an excellent building material, due to its outstanding weight-performance characteristics, its sustainable availability and its appearance generally perceived as very pleasant. For all these reasons, wood as main building component is very well suited for a lot of engineering structures. Nevertheless, it is not used as extensively and efficiently as these properties would suggest. The inherent heterogeneous material structure and the great diversity of species make wood a challenging material as regards computational mechanical and engineering design models. Thus, the potential of wood, wood-based products, and timber building components is not fully exploited yet. Limits in existing design methods hamper a reliable and economically competitive design of timber structures. The use of modern computational methods is expected to complement experimental investigations and to enhance the predictive capability of design methods for wood and wood-based products as well as for timber engineering.
Challenges are for example the appropriate description of complex brittle and ductile failure modes (triggered by the anisotropic material behaviour), the resulting load transfer mechanisms (specifically in the case of reinforcements), and a realistic determination of compliances of connections between timber components. For all this, the time-, moisture- and temperature-dependency of wood may be taken into account. To address these challenges, detailed knowledge of the mechanical behaviour of wood on different length scales, from the ‘cell wall material’ over ‘wood-based products’ up to ‘timber structures’, must be gained, brought together in modern mechanical modelling strategies, and finally transferred to engineering practice.
The resulting goal of this ECCOMAS Thematic Conference is to establish a platform for knowledge exchange between scientists in the field of computational wood mechanics. Related experimental and theoretical research as well as applied research up to design solutions for practical examples are also welcome, to extend the knowledge base of this unique material.
Thus, the scientific and technical areas covered by this conference are experimental investigations, numerical and analytical models, and design concepts for wood at different length scales, wood-based products, building components, and timber structures.
