Identification of anisotropic tensile strength of cortical bone using Brazilian test. [PDF]
, 2014 For a proper analysis of cortical bone behaviour, it is essential to take into account both the elastic stiffness and the failure criteria. While ultrasound methods allow complete identification of the elastic orthotropic coefficients, tests used to ...

Failure in Confined Brazilian Tests on Sandstone [PDF]
Applied Sciences, 2021 Strength of rocks in the confined tension region, where the minimum principal stress is tensile, has only infrequently been measured and is not well understood. Quasi-static confined Brazilian tests under a range of confining stresses (2.76 to 27.58 MPa) where used to determine the strength of sandstone in the confined tension region.

New approach of concrete tensile strength test
Case Studies in Construction Materials, 2020 The study aims to develop a new approach of concrete tensile strength test characteristic by minimizing the traditional drawbacks such as load eccentricity, stress or strain non-uniformity and stress concentration in traditional test methods and of a ...

DNA tests probe the genomic ancestry of Brazilians [PDF]
Brazilian Journal of Medical and Biological Research, 2009 We review studies from our laboratories using different molecular tools to characterize the ancestry of Brazilians in reference to their Amerindian, European and African roots. Initially we used uniparental DNA markers to investigate the contribution of distinct Y chromosome and mitochondrial DNA lineages to present-day populations.

A simple discrete-element-model of Brazilian test [PDF]
The European Physical Journal B, 2016 We present a statistical model which is able to capture some interesting features exhibited in the Brazilian test. The model is based on breakable elements which break when the force experienced by the elements exceed their own load capacity. In this model when an element breaks, the capacity of the neighboring elements are decreased by a certain ...
