As senior lecturer I aim for a balance between research activities, teaching and supervision tasks.

Teaching and research areas incorporate different disciplines related to the topic of wood mechanics and timber engineering. My core competency is a balanced knowledge base in experimental and numerical methods in mechanics, applied to the sustainable material wood. A knowledge base which I built-up during my research activities as PhD-student at the Vienna University of Technology (TU Wien), and is now extended and strengthen here at the Department of Building Technology at Linnaeus University. My doctoral thesis was dedicated to a combined experimental-numerical study on dowel joints in timber structures. A work which is resumed here at Linnaeus University and applied to new connection systems and wood products. Beside research it was and still is for me of highest relevance to transfer knowledge from science to industrial partners, our students and to the community.


Teaching activities are to a large extend related to the material wood. Thanks to a profound knowledge in wood mechanics, timber engineering and software supported design of structures, gained from research and previous teaching activities in the area of timber engineering, I can support colleagues in various courses at the undergraduate and graduate level, as well as in professional training. Among others these courses are: Building Technology, Water Supply and Wastewater Technology, Steel and Timber structures, Project work in detailed design, Professional training in Cross-laminated Timber structures. In addition, I am responsible together with a colleague for the master course Conceptual Structural Design. Furthermore, my academia work comprises supervision of Bachelor, Master and PhD-students.


My research is dedicated to experimental investigation and numerical modeling of wood and timber structures at different length scales, with a strong focus on connections in timber structures. This comprises combined experimental-numerical studies on wood materials, connection components, single-fastener connections, multiple-fastener joints, and analysis of timber structures. Advanced experimental and numerical methods of mechanics are used in scientific work to understand phenomena resulting in a deep knowledge on materials and structural systems, which are then used to develop engineering tools being applicable in building practice. This is achieved by close cooperation with industry partners, working groups related to standardization, and software developers. The aim of these cooperation philosophy is to combine scientific knowledge with practical experience, to achieve based on advanced numerical modeling, new enhanced design methods to facilitate timber structures as important part for a sustainable future.

    The database includes embedment parameters from in total 1565 tests, taken from 7 reports originating from ENSTIB/LERMaB Epinal, Vienna University of Technology (IMWS, TU Wien), Linnaeus University Växjö (LNU), TU Delft and Karlsruhe Institute of Technology (KIT).It compromises parameters from embedment test on 6 soft- and hardwood spieces, 4 wood-based products, 4 dowel diameter, loaded at 7 different load-to-grain angles.

    The embedment parameters can be used to describe load-displacement curves of steel dowels embedded in wood, being exploited in numerical models for single-dowel connections.

    Embedment parameters given in the database are explained and discussed in:Schweigler, M., T. K. Bader, J.F. Bocquet, and C. Sandhaas (2019). "Embedment test analysis and data in the context of phenomenological modeling for dowelled timber joint design." In: Proceedings of INTER/52-07-08 , Tacoma, USA.

    Update:2020-07-06: Parameters from embedment tests on birch (solid timber) are added Benistand, T. (2020).
