Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

open access: yesAdvanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Effect of molecular orientation on the fracture behaviour of carbon black filled natural rubber compounds

open access: yes, 2009
The fracture behavior of carbon black-filled natural rubber compounds, differing in filler content, was studied perorming tensile tests in biaxial loading conditions, using a central notched cross-shaped specimen.

Continuous Stiffness Graded Metal–Ceramic Femoral Stems: UMAT‐Based Design and Finite Element Assessment

open access: yesAdvanced Engineering Materials, EarlyView.
Functionally graded metal–ceramic femoral stems are engineered through continuous UMAT‐based stiffness tailoring, eliminating discrete material interfaces while enhancing biomechanical compatibility. Low‐index power‐law gradation optimizes load transfer, reduces stress shielding, and controls implant–bone micromotion, highlighting a materials‐design ...

The natural history of post-traumatic algodystrophy. [PDF]

open access: yes, 1990
Algodystrophy, particularly in it's less severe form, is a poorly recognised and ill understood condition which, when it occurs after fracture, delays rehabilitation.

Effect of natural fracture on hydraulic fracture propagation in poroelastic formation: fully coupled numerical model to investigate the interaction between induced and natural fracture

open access: yes, 2010
This thesis deals with modeling of an induced hydraulic fracture and a natural fracture in a poroelastic medium and study their interaction. A finite element based numerical model is developed for this purpose. The model integrates a wellbore, an induced

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Simulation of intersecting hydraulic fractures with natural fractures considering layer barrier effect

open access: yesYouqicang pingjia yu kaifa, 2022
At present, the hydraulic fracturing is a key technology for shale oil and gas exploitation. The natural fractures will be encountered in the process of compression fracture propagation, and the propagation characteristics of compression fractures after ...

Discrete Element Simulation of Interaction between Hydraulic Fracturing and a Single Natural Fracture

open access: yesFluids, 2019
Hydraulic fracturing (HF) treatment is performed to enhance the productivity in the fractured reservoirs. During this process, the interaction between HF and natural fracture (NF) plays a critical role by making it possible to predict fracture geometry ...

Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

open access: yesAdvanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.
