Thermal-Expansion and Fracture Toughness Properties ofParts made from Liquid Crystal Stereolithography Resins [PDF]

, 1998
Liquid crystal (LC) resins are a new kind ofstereolithography material that can produce parts with structured or ordered morphologies instead ofthe amorphous morphologies that result from standard resins.

Microscopic mechanism of loading rate of saturated coal sample mechanics and damage characteristics

Meitan kexue jishu, 2023
In order to explore whether the advance rate of the working face will have a secondary impact on the safe and efficient production of coal mine after coal seam water injection prevents impact pressure and relieves the danger, uniaxial compression tests ...

Thermal Fatigue Damage and Residual Mechanical Properties of WCu45/FeCr18Ni9 Steel Brazed Joint with NiCrSiBFe Filler Metal [PDF]

Archives of Metallurgy and Materials, 2020
Thermal fatigue properties of WCu45/FeCr18Ni9 steel brazed joint with Ni-Cr-Si-B filler metal were investigated. Results indicated that the fatigue damage of Ni-based joint was aggravated with the increased of thermal fatigue cycles times.

How Geometry Controls the Tearing of Adhesive Thin Films on Curved Surfaces [PDF]

, 2011
Flaps can be detached from a thin film glued on a solid substrate by tearing and peeling. For flat substrates, it has been shown that these flaps spontaneously narrow and collapse in pointy triangular shapes. Here we show that various shapes, triangular,

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Downscaling of fracture energy during brittle creep experiments [PDF]

, 2011
We present mode 1 brittle creep fracture experiments along fracture surfaces that contain strength heterogeneities. Our observations provide a link between smooth macroscopic time-dependent failure and intermittent microscopic stress-dependent processes.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

Advanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

Advanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Statistical Morphology and Fragment Mapping of Complex Proximal Humeral Fractures

Medicina, 2023
Background and Objectives: Proximal humerus fractures (PHFs) are common in the elderly, but the treatment results are often poor. A clear understanding of fracture morphology and distribution of cortical bone loss is important for improved surgical ...
