Pull-out creep laboratory test for soft rocks

International Journal of Rock Mechanics and Mining Sciences, 2021
Abstract This research introduces a laboratory creep test for measuring displacements in anchors embedded in large-scale soft rock samples (745 × 550 × 310 mm) under constant load for long periods. Here, the preliminary theoretical fundamentals that have served for the design of the equipment are detailed, together with its mechanical and geometrical

Pull-out test analysis for geo-reinforcement

Geotextiles and Geomembranes, 1999
Abstract Pull-out tests are extensively used to simulate the soil-reinforcement interaction mechanism along the interface. A simplified analysis for evaluation of the interaction mechanism in a general pull-out test is proposed for geo-reinforcement.

Pull-out tests with fibre-metal systems

Composite Interfaces, 1995
Fibre pull-out experiments have been carried out to compare the behaviour of reactive and non-reactive fibre-reinforced metal systems. The test samples were made by melting the metal matrix in vacuum and lowering the fibre a known depth into the liquid.

Pull-out tests on handcrafted headed studs

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2019
The aim of this paper is to contribute towards better understanding of the behaviour of site-welded headed studs embedded in normal-weight concrete. The axial failure loads of these studs estimated by design codes and other calculation methods are conservative and inaccurate for concrete cone detachment.

Interfaces Studied by Electromechanical Pull-Out Testing

MRS Proceedings, 1996
ABSTRACTThe experimental technique of electromechanical pull-out testing is introduced to study the interface between fiber and matrix. The technique involves measuring both the contact electrical resistivity and the shear bond strength of a fiber-matrix interface.

Probabilistic analysis of a pull-out test

Materials and Structures, 2009
This paper presents a sensitivity analysis of the pull-out strength of reinforcement embedded in concrete. Considering both European and French design codes, this failure strength depends on the variability of uncertain parameters such as Young’s modulus of concrete and yield stresses of materials (concrete and steel); moreover, two failure modes can ...

Load Transfer Mechanism in Pull-Out Tests

Geosynthetics International, 1997
This paper presents a numerical method to predict soil-geotextile interface friction parameters. A strain softening model was used to simulate the relationship between shear stress and horizontal displacement at the soil-geotextile interface. Pull-out tests were performed on two types of geotextile, with different tensile stiffnesses, embedded in a ...

Internally Instrumented Soil Nail Pull Out Tests

2011
In order to evaluate the ultimate bond stress used in modelling soil nail behaviour for lateral support, soil nail pull out tests are conducted on the site. In the analysis of the test results it is assumed that the free length given to the test nail is completely free and that the load distribution along the grout body is uniform at failure.

Micro-Analysis Ballast-Geogrid Pull out Tests Interaction

Applied Mechanics and Materials, 2014
The discrete element method was used to simulate geogrid-reinforced ballast by pull out tests. Ballast particle was made of irregular clumps where its size and shape were considered by bonded spheres. The response of the ballast reinforced with geogrid under loading agrees with pull out experimental results.

Advances in pull-out testing and data analysis

Composites Science and Technology, 1991
Abstract In spite of the apparently unrealistic character of the single filament pull-out test when compared to the complexity of the composite material, much information can be derived that has to do with the most fundamental aspects of the fibre/matrix mechanical interaction.
