Development of a glass microbubble-based lightweight strain hardening cementitious composite (LW-SHCC): Experiment and numerical simulation

Case Studies in Construction Materials, 2023
In this study, lightweight strain hardening cementitious composites (LW-SHCC) was developed through mix proportion design and experimental tests. The modified Andreasen and Andersen (A&A) model was applied for dry materials mixture proportioning and ...

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Nonlinear finite element of FRP reinforced concrete structures. [PDF]

, 2012
reinforcement is a non-corrosive alternative to steel and is gaining popularity for use in reinforced concrete structures exposed to corrosive environments. A major difference between the two reinforcing materials is their behaviour at failure.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Rheological Modifiers in Optimizing Quick Nozzle Mixing Technology for 3D Concrete Printing [PDF]

Quickly mixing concrete at or near the printing nozzle is a new technique developed by the authors to improve 3D concrete printing technology. Quick nozzle mixing (QNM) solves the inherent problem in 3D concrete printing due to the opposing rheological ...

Promoting structural sustainable design through the influence of quality control assessments

Scientific Reports
In structural reliability assessments, the selection of suitable parameters for the definition of stochastic models of component properties—such as concrete compressive strength, steel yield strength or geometric dimensions—is a prime requirement ...

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

Advanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Concrete admixtures - sustainable concrete

Acta Polytechnica CTU Proceedings, 2022
Durability of concrete, an important part of the sustainability theme, was, is, and will be one of the main topics for large infrastructure projects like the Gotthard base tunnel. For such important structures a service life of more than 80 years is expected. The prevailing underground conditions like water ingress, aggressive waters etc.
