Cracked beams, beetles flying out of the roof trusses, rot and mold, twisted wooden planks, and other nightmares of wooden buildings users can only become a reality if no known binding wood requirements for the wooden construction. Several principles and important information on the required wood properties are brought to you by the Timber Institute in Prague.

Crack propagation analysis in multilayered pipes
Bareš, Pavel
The fracture behavior of multilayered pipes applied for water and gas distribution is analyzed in this paper. The attention is focused on numerical modeling of crack propagation through twolayered pipe. Special attention is paid to the influence of interface between the layers on fatigue crack growth. The analysis is performed under the assumption of validity of linear-elastic fracture mechanic. Numerical calculations are performed by finite element method (system ANSYS).
