Use of ultrasound for a historical objects investigation
Original language description
Not only performance of historical object itself, but also performance of building materials is investigated within construction and technical research. It is appropriate to use non-destructive testing methods to determine mechanical properties of material, because they leave almost no remains or damages after testing as the other methods do. A measuring of ultrasound velocity belongs among the most known methods and has been using for a long time. It is possible to detect hidden defects, cracks or heterogeneities and to determine an important mechanical property - dynamic modulus of elasticity, by this method. In the paper there is demonstrated use of the method for various materials in-situ and in the lab, also. In-situ testing was used for investigation of timber structure members of the Masaryk Railway Station in Prague during its reconstruction in 2011. A device used for tests was Sylvatest, a machine with special conical transducers designed for wood. The original aim of laborato
