Comparative Study on the Bond Strength between Direct Tensile Test and Indirect Tensile Test for Bonded Concrete Overlay [PDF]

Journal of The Korean Society of Civil Engineers, 2013
Bonded concrete overlay is a favorable maintenance method since the material properties are similar to existing concrete pavements. In addition, bonded concrete overlay has advantage of structural performance based on being bonded together, both for the overlay layer and the existing pavement which perform as one monolithic layer.

Tensile Properties and Tensile Failure Criteria of Layered Rocks

Applied Sciences, 2022
Rocks are less resistant to tension than to compression or shear. Tension cracks commonly initiate compression or shear failure. The mechanical behavior of layered rocks under compression has been studied extensively, whereas the tensile behavior still ...

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 Discussion about the Rod Position in the Splitting Tensile Tests on Hollow Concrete Blocks

Buildings, 2022
Different loading conditions cause different tensile stress patterns in masonry structures. Several studies related to masonry behavior use indirect tensile tests to obtain that value, where the splitting test from ASTM-C-1006 is usually employed.

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.
