Multiscale Modeling of Hole Damage Evolution During Dynamic Installation of Interference Bushings in CFRP

open access: yesPolymer Composites, EarlyView.
Multiscale modeling for dynamic installatioin. ABSTRACT The dynamic installation of metal interference bushings has demonstrated significant potential for improving the mechanical performance of carbon fiber‐reinforced polymer (CFRP) joints. However, the underlying mechanisms governing the remaining life enhancement remain insufficiently understood ...

Study of the Buckling Behavior of Completion Strings for Ultra-Deep Gas Wells

open access: yesShiyou jixie, 2020
Due to high wellbore temperature and pressure, ultra-deep high temperature and high pressure (HTHP) gas wells have a high downhole string buckling risk that are very likely to cause string failure and worsened washout etc. problems.

Influence of Temperature Dependent Properties on Tunneling Cracks in Multi‐Layer Polymer Thin Films

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Tunneling cracks severely compromise the mechanical integrity of multi‐layer polymer thin films on stiff substrates. Although previous models assume a constant elastic modulus, this study characterizes four candidate thermoset polymers. Their elastic modulus (E$$ E $$), coefficient of thermal expansion (CTE), and glass transition temperature ...

A boundary element approach to buckling of laminated plates subjected to arbitrary in-plane loading [PDF]

open access: yes, 2002
Laminated plate buckling is analyzed by the boundary element method (BEM). Ignoring bending stretching coupling, a solution is first sought for the membrane stresses due to arbitrary in plane loading.

Seismic Response of Existing Masonry‐Infilled RC Frame Structures Retrofitted with Steel Exoskeletons

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 14, Page 3593-3611, November 2026.
ABSTRACT Considering the needs for reducing carbon emissions and except for extreme cases of very degraded existing structures, research on technologies allowing continued use or upgrading of older buildings has become a priority topic. Generally, research on upgrading of reinforced concrete frame structures certainly has a prominent role, because of ...

A Novel MR Elastography Device for Preclinical Applications From Spheroids to Rodents: Design, Validation, and Performance Evaluation

open access: yesNMR in Biomedicine, Volume 39, Issue 11, November 2026.
MR elastography (MRE) noninvasively assesses tissue biomechanics, but preclinical research suffers from diverse hardware solutions, hindering reproducibility and comparability. This study introduces a versatile preclinical MRE device for imaging rodents, ex vivo samples, and spheroids/organoids.

Research on the Behavior of Coiled Tubing Running Based on Experiment

open access: yesShiyou jixie, 2018
The coiled tubing is subject to complex forces in downhole condition. The loads like gravity, liquid resistance, bending moment and torque, and environmental factors such as temperature and pressure make the coiled tubing prone to buckling during running.

Azobenzene's Cross‐Scale Optics and Photonics: Molecular Photoswitching, Mesoscopic Material Motions, and Adaptive Devices

open access: yesAdvanced Materials, Volume 38, Issue 56, 8 October 2026.
Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...
