“…The evolution of ω f is based on the crack-bridging model of Lin and Li [7] in which the debonding phase is assumed to be linear elastic. The expression of the fibre effective damage parameter ω f is evaluated using the 1D form of Eq.…”

“…A similar procedure is employed by Soroushian and Lee [37] to derive a theoretical expression for the number of fibres per unit cross-sectional area. Assuming a linear hardening relationship between the fibre-matrix interfacial shear stress ( ) and interfacial slip (S) respectively, Lin and Li [7] derived the pull-out force carried by a single fibre.…”

“…Several models that describe the pull-out of randomly distributed short fibres from a cementitious matrix have been proposed [1,2,[4][5][6][7]. Naaman et al [4,5] investigated the influence of fibre-matrix bond properties on the behaviour of FRCCs using an analytical model, since it had become apparent from experimental investigations that the behaviour of FRC, particularly in the post-cracking stage, was strongly influenced by the interfacial bond-slip response.…”

“…Assuming a linear-elastic -constant frictional bond-slip relationship they formulated a model that describes the whole pull-out process of a single fibre aligned with the pull-out force. Li et al [1], Li [2] and Lin and Li [7] derived a series of closed form analytical solutions that describe the pull-out of fibres that have 3-D uniform random distributions in location and orientation relative to the matrix crack plane. In these contributions, Li and co-workers considered a number of assumptions for the fibrematrix bond model, including constant interface shear stress (pure frictional behaviour) [2] or slipweakening [1] and slip-hardening behaviour [1,7].…”

A unique constitutive model for fibre reinforced concrete (FRC) is presented, which combines a number of mechanics-based sub models for the simulation of directional cracking, rough crack contact and the crack-bridging action of fibres. The model also contains a plasticity component to simulate compressive behaviour. The plasticity component employs a frictional hardening/softening function which considers the variation of compressive strength and strain at peak stress with fibre content. Numerical results from a range of single-point and finite element simulations of experimental tests show that the model captures the characteristic behaviour of conventional fibre reinforced concrete with good accuracy.

Biomineralized materials are sophisticated material systems with hierarchical 3D material architectures, which are broadly used as model systems for fundamental mechanical, materials science, and biomimetic studies. The current knowledge of the structure of biological materials is mainly based on 2D imaging, which often impedes comprehensive and accurate understanding of the materials’ intricate 3D microstructure and consequently their mechanics, functions, and bioinspired designs. The development of 3D techniques such as tomography, additive manufacturing, and 4D testing has opened pathways to study biological materials fully in 3D. This review discusses how applying 3D techniques can provide new insights into biomineralized materials that are either well known or possess complex microstructures that are challenging to understand in the 2D framework. The diverse structures of biomineralized materials are characterized based on four universal structural motifs. Nacre is selected as an example to demonstrate how the progression of knowledge from 2D to 3D can bring substantial improvements to understanding the growth mechanism, biomechanics, and bioinspired designs. State‐of‐the‐art multiscale 3D tomographic techniques are discussed with a focus on their integration with 3D geometric quantification, 4D in situ experiments, and multiscale modeling. Outlook is given on the emerging approaches to investigate the synthesis–structure–function–biomimetics relationship.

Die Frage der sicheren und sinnvollen Verankerung von textiler Bewehrung im Beton beschäftigt nicht nur Anwender des innovativen Verbundwerkstoffs Carbonbeton. Auch in der Forschung sind für die Thematik des Verbunds und der Verankerung wesentliche Fragen nicht abschließend geklärt. Bisher existiert kein Bemessungsmodell für die Verankerung oder Übergreifung, welches bei der derzeit verfügbaren Bandbreite textiler Bewehrungen mit weicher bis steifer Tränkung gleichermaßen gültig ist. Die unterschiedlichen Versagensmechanismen des Verbunds, die aus den Charakteristika der Materialien resultieren, werden selten klar unterschieden. Dieser Artikel verdeutlicht die Auswirkungen des Formschlusses auf das Verankerungsverhalten am Beispiel einer textilen Bewehrung mit steifer Tränkung und ordnet Ergebnisse von experimentellen Untersuchungen in die bisherige Forschung ein. Hierzu wird ein Prüfaufbau für einen Auszugversuch vorgestellt, welcher auch zur Abschätzung des Verankerungsverhaltens in Praxisprojekten und zur Qualitätskontrolle in der Produktion genutzt werden kann.
