Mixed-Mode I + II fracture characterization of bonded joints using a novel Multi-Mode Apparatus [PDF]

, 2014
The present work presents the experimental test results to assess the toughness of an adhesive joint, using a previously defined crack equivalent data reduction scheme applied to a new multi-mode apparatus, inspired in a load jig previously developed by ...

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

Advanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

Full‐Field Damage Monitoring in Architected Lattices Using In situ Electrical Impedance Tomography

Advanced Functional Materials, EarlyView.
In situ electrical impedance tomography (EIT) turns 3D‐printed, CNT‐infused architected lattices into full‐field damage‐imaging systems. Tunable Voronoi‐based geometries act as active sensing architectures, enabling conductivity maps to detect early‐stage damage and localise sequential ligament fracture before catastrophic failure.

A new data reduction scheme to obtain the mode II fracture properties of Pinus Pinaster wood [PDF]

, 2006
In this work a numerical study of the End Notched Flexure (ENF) specimen was performed in order to obtain the mode II critical strain energy released rate (GIIc) of a Pinus pinaster wood in the RL crack propagation system.

Analog Classification of Human Hand Gestures Exploiting Dendritic Integration With an Organic Artificial Soma

Advanced Functional Materials, EarlyView.
An organic neuromorphic architecture for the classification of human motor behavior is presented and validated. It performs somatic integration by linearly combining the activity from three muscles. An investigation of synaptic weights is presented and discussed in relationship with the classification performance.

The relationships between tensile strength, mode I and mode II fracture toughness of rock: An empirical and microcracking perspective

Heliyon
The empirical relationships between tensile strength, mode I and mode II fracture toughness obtained by previous studies have the problem of a small amount of data for fitting, and more data are needed for further study.

Particle‐Level ZrO2 Atomic Layer Deposition Enables Fast‐Cycling and Long‐Life Graphite Cathodes for Dual‐Ion Batteries

Advanced Functional Materials, EarlyView.
A spatial location of atomic layer deposition (ALD)‐derived ZrO2 coatings is demonstrated to be a critical design parameter for stabilizing graphite cathodes in DIBs. Direct particle‐level ALD (PALD) screening of representative metal oxides identified ZrO2 as the coating that provides the most favorable balance of high‐rate capability and interfacial ...

Investigating dynamic mixed-mode I/II fracture behavior of sandstone using the modified generalized maximum tangential stress criterion

Journal of Rock Mechanics and Geotechnical Engineering
Dynamic mixed-mode I/II crack growth under various engineering disturbances can result in rock failure and even catastrophic events. Nevertheless, the dynamic cracking behaviour of rock and fracture criterion for mixed-mode I/II remain poorly understood.

Mixed mode (I + II) fracture toughness of polymer nanoclay nanocomposites

, 2013
In this work the mixed mode fracture behaviour (I + II) of an epoxy/nanoclay nanocomposite system is analysed, discussing the results from Single Edge Notch Bending tests. It is found that nanomodification significantly enhances the fracture toughness of
