The Influence of Deformation of the Frame of Testing Device on the Accuracy of Brazilian Test and Indirect Assessment of Young Modulus
Š. Major, D. Vavřík, V. Kocour, J. Bryscejn
pages 188 - 189, full text

This article deals with determination of mechanical properties based on indirect measurements of brittle building materials like stones using portable device. Due to the fact, that the material samples may change their properties during transportation, it is preferred to test samples on site. For these reasons, portable testing device was developed. The testing machine operates on the split test principle. The device also shall to serve for estimation of other mechanical characteristics of the tested material, such as Young's modulus, compressive strength or flexural strength, etc. This paper concentrates on the effect of deformation of frame on the accuracy of indirect determination of mechanical properties.
