Digital Image Correlation technique applied to mechanical characterisation of aluminium foam

EPJ Web of Conferences, 2010
In this paper the possibility to employ the Digital Image Correlation (DIC) technique for the mechanical behaviour analysis of metallic foam was investigated. Image Correlation allowed to measure displacement and strain fields on closed and open cells

i‐Tac: Inverse Design of 3D‐Printed Tactile Elastomers with Tuneable Optical and Mechanical Properties

Advanced Intelligent Systems, EarlyView.
Inspired by the multi‐tissue architecture of the human fingertip dermis (A), this work introduces a mixture design using three PolyJet materials (AC/TM/GM) to expand the achievable elastomer property space (B). An inverse design pipeline (i‐Tac) is developed to map target optical/mechanical requirements to optimal material compositions (C), enabling ...

Predominance of Ferroptotic Cell Death Mechanisms in Substantia Nigra Neurodegeneration in Parkinson's Disease

Annals of Neurology, EarlyView.
Objective The extent of neuronal loss in Parkinson's disease (PD) and the pathogenic processes underlying neuronal dysfunction and loss remain poorly understood. Here, we analyzed the expression of key molecules representing different cell death signaling pathways and their association with Lewy pathology, dopaminergic (DA) neuron loss and stage of PD ...

Uniaxial Static Stress Estimation for Concrete Structures Using Digital Image Correlation

Sensors, 2019
This paper proposes a static stress estimation method for concrete structures, using the stress relaxation method (SRM) in conjunction with digital image correlation (DIC). The proposed method initially requires a small hole to be drilled in the concrete

C‐Terminal Nucleobase Modification Amplifies Peptide‐Mediated Liposome Fusion

Chemistry – A European Journal, EarlyView.
Let's come together right now. Cationic peptides are known to promote aggregation of negatively charged liposomes through electrostatic interaction. The process is reversible: once neutrality is achieved, liposomes disaggregate. Here, we demonstrate that end‐capping peptides with nucleobases turns the process into irreversible fusion.

Strain Accumulation in TiAl Intermetallics via High-resolution Digital Image Correlation (DIC)

Procedia Engineering, 2014
AbstractNovel manufacturing process are more and more used to produce advanced structural materials such as the gamma titanium aluminide alloys (γ-TiAl). In this work we examine a Ti-48Al-2Cr-2Nb alloy obtained with an additive manufacturing technique by Electron Beam Melting (EBM) by conducting monotonic and cyclic loading experiments both on tension ...

Dynamic tensile strength and fracture evolution of characteristic shale with bedding and hole using linear regression theory

Deep Underground Science and Engineering, EarlyView.
The spiral conical perforations generated during methane in situ explosion fracturing operations lead to tensile fracture propagation in shale reservoirs being governed by the combined effects of impact pressure, bedding, and aperture under explosive loading. Using multiple regression analysis and digital image correlation technology, the mechanisms of
