Direct Tensile Test on Brittle Rocks with the Newly Developed Centering Apparatus [PDF]

Geotechnical Testing Journal, 2017
Abstract Failure of brittle rock normally initiates from tensile fracture due to its extraordinary lower resistance to tension rather than to compression. Intensive study on the deformability and accurate acquirement of the mechanical properties of rock under tensile stress is crucial for the stability analysis of rock slope and rock ...

3action: Advances in direct-tensile testing of concrete

Materials and Structures
Abstract Gaining a deeper insight into stress vs crack opening curve of concrete is essential, especially when crack stability governs the durability and the capacity of a structure. Despite its rationality, the direct-tension test faces the challenges entailed by strain-softening materials, namely axial and flexural instability.

Indirect Tensile Strength Test on Heterogeneous Rock Using Square Plate Sample with a Circular Hole [PDF]

Lithosphere
An indirect testing method for determining the tensile strength of rock-like heterogeneous materials is proposed. The realistic failure process analysis method, which can consider material inhomogeneity, is applied to model the failure process of the ...

A Direct Measurement Method for the Uniaxial Tensile Strength of Rock

Buildings
A universally applicable direct tension test method is proposed in this paper based on the concept of “compression-to-tension”. Using this method, one or two typical rocks were selected for each of the three types of rocks.

A COMPARISON OF TESTING METHODS FOR DETERMINATION OF SPRAYED CONCRETE TENSILE STRENGTH

Acta Polytechnica CTU Proceedings, 2019
Sprayed concrete is important construction material in tunnelling. Primary lining is essential in NATM where the sprayed concrete can be loaded by tension due to bending moments.

Neurovascular Contacts in the Pathophysiology of Neuralgic Amyotrophy: An Observational Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuralgic amyotrophy (NA) is a prevalent, monophasic, multifocal immune‐mediated neuropathy. A distinctive characteristic of the disease is the occurrence of nerve or fascicle constrictions and torsions (NA‐associated focal nerve lesions, NAFL). The pathophysiology underlying this phenomenon remains to be fully elucidated.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing
