On Applicability of Some Indirect Tests for Estimation of Tensile Strength of Anisotropic Rocks
The tensile strength of rocks plays a noteworthy role in their failure mechanism, and its determination can be beneficial in optimizing the design of the rock structures. Schistose rocks due to their inherent anisotropy in different foliation directions show a diverse strength at each direction. The purpose of this work was to compare and assess the tensile strength of phyllite, which was obtai...
متن کاملTensile and Creep Testing of Sanicro 25 Using Miniature Specimens
Tensile and creep properties of new austenitic steel Sanicro 25 at room temperature and operating temperature 700 °C were investigated by testing on miniature specimens. The results were correlated with testing on conventional specimens. Very good agreement of results was obtained, namely in yield and ultimate strength, as well as short-term creep properties. Although the creep rupture time was...
متن کاملNumerical study of strength mismatch in cross-weld tensile testing
The strength mismatch effect on the deformation behaviour of defect-free cross-weld tensile specimens, where there is a variation in strength along the length of the specimen, was investigated through 2D finite element analysis. A simple bi-material model, which is generally used in current engineering assessments (e.g. R6 “Assessment of the integrity of structures containing defects”) to exami...
متن کاملTensile Strength Properties of Tropical Hardwoods in Structural Size Testing
In Malaysia, there is no research done on the tensile strength of structural size timber. The tension stress found in the Malaysian code of practice, MS 544: Part 2: 2001, was not determined directly and it was taken as 60% of the bending strength values of small clear specimens. This paper presents the results of the tensile test on structural size timber specimens from selected Malaysian Trop...
متن کاملStress Non-uniformity in Hollow Cylindrical Test Specimens
Different levels of stress non-uniformity usually occur in test specimens of different dimensions and aspect ratios. The effect of the choice of dimensions on the level of stress nonuniformity for hollow cylindrical specimens was studied using a linear elastic analysis during the development of a new hollow cylinder apparatus. Earlier researchers have assumed slightly different variations in th...
