Mechanical State Model of Multispan Continuous Deep Beam under Concentrated Load [PDF]

Mathematical Problems in Engineering, 2013
Summary: In the present study, the mechanical model of the multispan continuous deep beam under concentrated load was established on the state space theory, and with the model, the two-span continuous deep beam was calculated. And the calculation results are consistent with ANSYS results, which show that the model without the plane section assumption ...

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Structural Response of Continuous High-Strength Concrete Deep Beams with Rectangular Web Openings

Buildings
Openings are often introduced in continuous reinforced concrete (RC) deep beams to accommodate utility services, which can compromise their structural capacity. This paper presents a numerical investigation—via nonlinear finite element (FE) modeling—into

Loading Capacity Prediction of Rubberized Reinforced Concrete Continuous Deep Beams

IOP Conference Series: Materials Science and Engineering, 2021
Abstract Results of fourteen two-span continuous concrete deep beams were presented and discussed in this research. One sample was designed as a reference to be an ordinary reinforced concrete beam (ORC) while thirteen samples were made of rubberized concrete (RRC). The investigated parameters were the shear span/overall depth ratio (a/h)

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Nonlinear Behavior of Reinforced Concrete Continuous Deep Beam

International Journal of Engineering Research and, 2015
This paper presents numerical investigation of nine continuous reinforced concrete deep beams were experimentally tested and collected from literature. The collected specimens cover several parameters which usually influenced on strength and behavior of continuous deep beams as shear span to depth ratio, the reinforcement ratio, the effective depth ...

Effectiveness of Web Reinforcement around Openings in Continuous Concrete Deep Beams [PDF]

ACI Structural Journal, 2008
Reinforced concrete deep beams frequently have openings to facilitate essential services, but there has been little research and few code provisions for continuous deep beams with different web reinforcement arrangement around web openings. In this paper, 22 reinforced concrete continuous deep beams with openings and two companion solid deep beams were

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Multimodal Data‐Driven Microstructure Characterization

Advanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.
