Impact bending strength of Finnish tree species in green condition

Impact bending strength of Finnish tree species in green condition

There are great impact forces in mechanized harvesting and wood yard in the mills which can cause breaks in timber. The impact strength of timber in green condition was tested in temperatures of +18°C and -18°C using sawn pieces (20 x 20 x 300 mm) of Scots pine ( L.), Norway spruce ( (L...
