A model for strength and strain analysis of steel fiber reinforced concrete / Betono, armuoto plienine dispersine armatura, stiprio ir deformaciju apskaiciavimo modelis

open access: yesJournal of Civil Engineering and Management, 2011
The article proposes a model for strength and stain analysis of steel fiber reinforced concrete (SFRC). The model is based on general principles for creating and modelling structural composites and on reinforced concrete code.

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

open access: yesAdvanced 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.

Shear resistance of reinforced concrete beams with and without steel fibres. [PDF]

open access: yes, 1981
The fabrication and placement of conventional shear rein- forcement are time consuming and costly and its use in thin structural concrete members is often impractical.

Ground Motion Model for Spectral Displacement of Intermediate-Depth Earthquakes Generated by Vrancea Seismic Source

open access: yesGeosciences, 2020
In support of displacement-based design (DBD), an attenuation model for the prediction of the spectral displacement of intermediate-depth earthquakes generated by Vrancea source is proposed.

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

open access: yesAdvanced 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.

Shear capacity of reinforced concrete beams using neural network [PDF]

open access: yes, 2007
NoOptimum multi-layered feed-forward neural network (NN) models using a resilient back-propagation algorithm and early stopping technique are built to predict the shear capacity of reinforced concrete deep and slender beams.

Optimum reinforcement design of concrete cross‐sections considering deformation constraints

open access: yesJournal of Civil Engineering and Management, 2005
The paper concerns the optimum reinforcement design for r/c cross‐sections through the simultaneous consideration of multiple load cases. The problem is solved by methods of non‐linear mathematical programming.

Reinforced concrete reinforcement

open access: yes, 2020
The article deals with the problems of reinforcement of reinforced concrete structures with the help of plastic reinforcement. The use of reinforcement in reinforced concrete has many methods, and calculation of their strength depends on the expected level of stress on the structure. Proceeding from the fact that the armature is flexible or rigid steel

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.
