Wedge splitting test for a steel–concrete interface
Abstract This paper presents a test method designated for the determination of the stress–crack opening relationship of a steel–concrete interface. The method is based on the well known wedge splitting test (WST), and it is illustrated how to obtain the stress–crack opening relationship through an inverse analysis.

On the equivalence of two deformation schemes in quantum field theory [PDF]
Two recent deformation schemes for quantum field theories on the two-dimensional Minkowski space, making use of deformed field operators and Longo-Witten endomorphisms, respectively, are shown to be equivalent.Comment: 14 pages, no figure.

Extraction of biological hydroxyapatite from tuna fish bone for biomedical applications [PDF]
Natural hydroxyapatite (HAp) is known for its common use in biomedical applications including in orthopaedic and implantation. HAp can be extracted from natural resources such as eggshells, fish bones and coral.

Experimental Study on High-Energy Gas Fracturing Artificial Coal
The low permeability of coal seams has always been the main bottleneck restricting coalbed gas drainage. To improve the permeability of a coal seam, a high-energy gas fracturing technology is proposed.

Analysis of wedge splitting test on refractory castable via integrated DIC [PDF]
One of the key mechanical properties of refractories is their toughness. The latter can be evaluated via wedge splitting tests. One such test is analyzed herein with an integrated approach to digital image correlation. The position of the crack tip, stress intensity factors and T-stress are estimated on two faces of the tested sample made of a ...

Analysis of accuracy of Williams series approximation of stress field in cracked body – influence of area of interest around crack-tip on multi-parameter regression performance [PDF]
A study on the accuracy of an approximation of the stress field in a cracked body is presented. Crack-tip stress tensor is expressed using the linear elastic fracture mechanics (LEFM) theory in this work, more precisely via its multi-parameter ...
