Two-dimensional quasi-static delamination in composite laminates under Mode-I and Mode-II conditions
Fiber-polymer composites consist of a polymer matrix and reinforcing fibers made of various materials. These composites exhibit exceptional properties, such as a high strength-to-weight ratio and excellent corrosion resistance, which has led to their incre ...
EPFL2024A novel fatigue life prediction methodology based on energy dissipation in viscoelastic materials, synergistic effects of stress level, stress ratio, and temperature
Thomas Keller, Lulu Liu, Abdolvahid Movahedirad
This work introduces a new methodology to predict the fatigue life of viscoelastic materials by considering the creep effect on fatigue behavior under the concurrent effects of stress level, stress ratio, and temperature. The model established based on the ...
2024Numerical investigation of two-dimensional Mode-II delamination in composite laminates
Thomas Keller, Anastasios Vassilopoulos, Congzhe Wang
Delamination in real composite structures, which generally tends to grow in two-dimensions, sometimes cannot be appropriately represented by the widely accepted test methods where one-dimensional (1D) beam specimens are typically employed. In order to comp ...
2024Numerical investigation of two-dimensional Mode-II delamination in composite laminates
Thomas Keller, Anastasios Vassilopoulos, Congzhe Wang
Existing standards for delamination tests on composite materials typically employ one-dimensional (1D) beam specimens. However, such specimens may not represent real delamination scenarios in composite structures, where cracks tend to propagate in two dime ...
London2024Density and phase-purity of α-TCP obtained by sintering of nano-crystalline powder
Andrea Testino, Christoph Stähli
Dense and polished samples are sometimes used to test the in vitro biological response of biomaterials. However, their production can be challenging, for example for α-tricalcium phosphate (α-TCP), a commonly-used bone graft substitute. In this particular ...
2024Large-Scale Hollow-Core 3D Printing: Variable Cross-Section and Printing Features for Lightweight Plastic Elements
Hollow-core 3D printing (HC3DP) proposes a new method for the production of lightweight, material-efficient thermoplastic 3D printed elements. This new fabrication approach promises material savings of 50-80%, while increasing the extrusion rate significan ...
Mary Ann Liebert, Inc2024Novel multi-crack damage approach for pultruded fiber-polymer web-flange junctions
This paper aims to propose a novel approach to assess the multi-crack behavior of layered fiber-polymer composites. The Compliance and R-curves generated from this novel approach were useful to understand the multiple delamination process, enabling to eval ...
London2023The Development of Aptamer-Coupled Microelectrode Fiber Sensors (apta-?FS) for Highly Selective Neurochemical Sensing
The selective and sensitive sensing of neurochemicals is essential to decipher in-brain chemistry underlying brain pathophysiology. The recent development of flexible and multifunctional polymer-based fibers has been shown useful in recording and modulatin ...
AMER CHEMICAL SOC2023Energy dissipation in fiber-polymer composites adhesive joints under cyclic loading
Sustainable development has emerged as a paramount consideration in various fields of industry, including construction, to preserve the environment and its finite resources. Lightweight structures, such as fiber-polymer composite structures, address both s ...
EPFL2023Influence of Fiber Orientation on the Elastic Limit Tensile Stress of UHPFRC
Eugen Brühwiler, Emmanuel Denarié, Jian Zhan
The elastic limit tensile stress of UHPFRC is governed by contributions of the cementitious matrix and the fibrous skeleton. This paper finds that fiber orientation has significant influence on the matrix tensile strength of UHPFRC, while this is not consi ...
