In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy

Advanced Engineering Materials, EarlyView.
A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

A dynamic convergence control scheme for the solution of the radial equilibrium equation in through-flow analyses [PDF]

, 2010
One of the most frequently encountered numerical problems in scientific analyses is the solution of non-linear equations. Often the analysis of complex phenomena falls beyond the range of applicability of the numerical methods available in the public ...

Toward Knowledge‐Based Workflows: A Semantic Approach to Atomistic Simulations for Mechanical and Thermodynamic Properties

Advanced Engineering Materials, EarlyView.
Knowledge‐based atomistic workflows are presented for mechanical and thermodynamic properties. By coupling modular simulations with ontology‐aligned metadata and provenance, Fe case studies on elastic behavior, defects, thermal properties, and Hall–Petch strengthening reveal how FAIR, queryable, and reusable simulation data can be generated. Mechanical

Study on the Mechanical Properties of Composite Special-Shaped Columns with RAC-Filled Square Steel Tubes

Metals
The L-shaped columns of recycled aggregate concrete-filled steel tubes (L-RACFSTs) with a 40% coarse aggregate replacement ratio were selected as the research subject, and axial compression and eccentric compression tests were conducted.

Effect of axial compression ratio on seismic behavior of hybrid FRP-steel reinforced concrete columns

Concrete columns reinforced with hybrid longitudinal steel-fiber reinforced polymer (FRP) composite bars (SFCBs) and FRP stirrups (hybrid-RC columns) are attractive for marine concrete structures due to exceptional corrosion resistance and mechanical ...

Axial-strain sonoelastography of the Achilles tendinopathy: diagnosis, prevention and treatment monitoring

, 2017
Compression elastography or axial-strain sonoelastography (SE) is a relatively new ultrasound (US) based technique that estimates the stiffness or softness of a tissue by measuring the strain (displacement) caused by tissue compression.

Cathodic Cage Plasma Deposition of Nanostructured Cu–Fe–Se Coatings on Poly(methyl Methacrylate)

Advanced Engineering Materials, EarlyView.
Nanostructured Cu–Fe–Se coatings are deposited on PMMA by a modified cathodic cage plasma process, enabling low‐temperature deposition on polymer substrates. A transition from discontinuous to compact morphology is observed with temperature, with optimal properties at 200°C, where improved CuFeSe2‐type bonding, lowest sheet resistance, and favorable ...

The Influence of Axial Compression Ratio on Seismic Behavior of SRUHSC Frame under Cyclic Loading

KSCE Journal of Civil Engineering, 2019
In this paper, the seismic behavior of Steel Reinforced Ultra-High Strength Concrete (SRUHSC) frames is experimentally studied under cyclic loading. Three one story-one span frames are carried out, and the main parameter is axial compression ratio.

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

Advanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Axial Compression-Flexure Interaction Behavior of Hybrid FRP-Strengthened Columns

, 2019
Fiber-reinforced polymer (FRP) composites are widely used for strengthening of reinforced concrete (RC) elements under different loading conditions. This paper aims at understanding the axial compression-bending moment (P-M) interaction behavior of RC ...
