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).
