1. EU HARDWOODS Progress report from UL FGG Paris meeting Goran Turk (UL FGG) Mitja Plos (UL FGG) Ur ka Bajc (UL FGG)

2. Univerza v Ljubljani Fakulteta za gradbeni tvo in geodezijo LITERATURE SURVEY The extensive literature of the dissertation from Ulrich H bner has been checked for existing data on mechanical properties of hardwood species Data from only 7 papers was taken (Aicher, Bachle, Blass, Frese, Fruhwald, Glos, Lanvin) Further research will be done on other more recent publications Additional testing will be done within the project on Slovenian beech

4. Univerza v Ljubljani Fakulteta za gradbeni tvo in geodezijo FURTHER TESTING Expand the data with visual, non-destructive and destructive data for single lamellas Within the EU Hardwoods project tension tests will be done Later bending tests on single lamellas and on glulam beams will also be done

5. Univerza v Ljubljani Fakulteta za gradbeni tvo in geodezijo FURTHER TESTING - Material Beech wood (Fagus sylvatica) from Slovenia 200 logs from sawmill GG Novo Mesto d.d. Minimal length 3 m

6. Univerza v Ljubljani Fakulteta za gradbeni tvo in geodezijo FURTHER TESTING - Sample 4 pieces from each log = 800 pieces Dimensions: 48 mm x 150 mm 200 pieces for tension tests on single lamellas (EU Hardwood) 200 pieces for bending tests on single lamellas 400 pieces for the production of glulam beams

7. Univerza v Ljubljani Fakulteta za gradbeni tvo in geodezijo FURTHER TESTING - Glulam 40 glulam beams 5 lamellas per height Glulam beams dimensions: 150 mm x 240 mm x 5000 mm Glulam beams production at glulam company HOJA d.d.

8. Univerza v Ljubljani Fakulteta za gradbeni tvo in geodezijo FURTHER TESTING NDT + Destructive tests Visual grading (DIN 4074-5, KAR, BS 5756) Longitudinal Eigen frequency Transverse Eigen frequency Speed of ultrasound Destructive testing

9. Univerza v Ljubljani Fakulteta za gradbeni tvo in geodezijo DISSEMINATION Project logo LinkedIN project page Updated web page Presentation of the project at a small WoodWisdom-NET+ conference in Slovenia (second year round) FVA will present a paper at the International Scientific Conference on Hardwood Processing in Quebec City
