BENDING TESTS ON TIMBER CONCRETE COMPOSITES WITH PERFOBOND CONNECTIONS Hasselt University
Long spans in timber concrete composites (TCC) is the next step of improvement that is ambitioned by the industry and designers for more efficient structures. With Perfobond connections, which are originally developed for steel-concrete composites (SCC) constructions, targeting longer spans in TCC is feasible. In this paper, full scale TCC beams are experimentally investigated under four point bending with the use of Perfobond connections. Two ...
The round panel and 3-point bending tests KU Leuven
The postcracking tensile strength of fibre reinforced concrete must be determined experimentally. Best known test methods are the 3-point bending test (EN 14651:2005), the uniaxial tension test, the 4-point bending test and the wedge splitting test. All these test methods show a large scatter on the test results which is due to the non-uniform fibre distribution and the rather small cracked area in the specimen. As a result, one of the possible ...
Large scale bending tests on soil mix elements KU Leuven
© ASCE 2015. Since several decennia, the deep mixing method has been used to improve the strength and deformation characteristics of soft soils. A more recent trend is the use of this technique for the construction of soil mix walls designed as soil and water retaining structures. Within the framework of the BBRI Soil Mix project (2009-2013), seventeen large-scale bending tests have been performed on excavated soil mix elements previously ...
Tissue modulus derived from beam theory is biased by bone size and geometry: implications for the use of three-point bending tests to determine bone tissue modulus KU Leuven
Current practice to determine bone tissue modulus of murine cortical bone is to estimate it from three-point bending tests, using Euler-Bernoulli beam theory. However, murine femora are not perfect beams; hence, results can be inaccurate. Our aim was to assess the accuracy of beam theory, which we tested for two commonly used inbred strains of mice, C57BL/6 (B6) and C3H/He (C3H). We measured the three-dimensional structure of male and female B6 ...
Investigation of 3D TRC's by Means of Three Point Bending Tests on Short Beam Specimens Vrije Universiteit Brussel
Textile reinforced cements (TRC), combining a cementitious matrix with fibre textiles, are a well-researched subject in literature. The material offers several advantages such as the design of low-weight, slender structures. However, one of the main drawbacks of this composite material is the time consuming manufacturing process using two dimensional fibre textiles. Three dimensional
fibre textile architectures offer a solution to this ...

In-situ scanning electron microscopy study of fracture events during back-end-of-line microbeam bending tests KU Leuven
This paper demonstrates the direct observation of crack initiation, crack propagation, and interfacial delamination events during in-situ microbeam bending tests of FIB milled BEOL structures. The elastic modulus and the critical force of fracture of the BEOL beam samples were compared for beams of different length and width.
Dispersion of the mechanical properties of FRC investigated by different bending tests KU Leuven
© 2008 Taylor & Francis Group, London. Fibres are well known to provide post-cracking energy to concrete, enhancing the energy absorption capacity (toughness) of the material. However, variations of toughness performances of FRC are a well-known limitation for its use in structural applications. This shortcoming is not only caused by the heterogeneity of the material itself. It is also emphasized by the test method used to determine the FRC ...
