Optimal notched specimen parameters for accurate fatigue critical distance determination

Procedia Structural Integrity, 2017
Abstract The critical distance value should theoretically be determined from the plain specimen fatigue limit and the threshold stress intensity factor, though usually ordinary notch geometries are considered. In this paper, we proposed an optimized sharp notch with the aims of simple and reliable manufacture and, more importantly, a local strong ...

Optimal Design for a Novel Compliant XY Platform Integrated with a Hybrid Double Symmetric Amplifier Comprising One-Lever and Scott–Russell Mechanisms Arranged in a Perpendicular Series Layout for Vibration-Assisted CNC Milling

Micromachines
Compliant mechanisms are often utilized in precise positioning systems but have not been thoroughly examined in vibration-aided fine CNC machining. This study aims to develop a new 02-DOF flexure stage for vibration-aided fine CNC milling.

Optimized Specimen for Paperboard Shear Delamination Testing

Experimental Mechanics
Abstract Background The out-of-plane shear behavior of paperboards plays a critical role in converting processes such as creasing and folding. The recently proposed Split Double Cantilever Beam (SDCB) specimen has been used to characterize this behavior using a cohesive zone model, but its ...

Optimized Delta Check Rules for Detecting Misidentified Specimens in Children

American Journal of Clinical Pathology, 2019
AbstractObjectivesPreanalytical processes in pediatric patients are generally manual and associated with a higher risk of error. The optimized delta check rules for detecting misidentified children samples are examined.MethodsRelative difference and absolute different delta check limits were applied on original and reshuffled (to simulate sample ...

Image-based high strain-rate testing for the characterization of viscoplasticity

EPJ Web of Conferences, 2018
The present work aims at identifying an elastic-viscoplastic material behaviour over a wide strain and strain-rate range (up to 0.1 and 1000 s-1 respectively), using the so-called Virtual Fields Method.

Comparison and optimization for DNA extraction of archived fish specimens

MethodsX, 2019
The DNA extracted from museum alcohol-fixed specimens can be a valuable source of information for solving taxonomic, phylogenetic, ecological and conservational questions. However, this type of DNA, also called ancient DNA, is routinely obtained in small portions and highly fragmented.

Multi-Material Optimization for Lattice Materials Based on Nash Equilibrium

Applied Sciences
Lattice materials are regarded as a new family of promising materials with high specific strength and low density. However, in the optimization of lattice materials, it is difficult in general to determine the material distribution in lattice structures ...

A digitization workflow of dry-pinned collections of Lepidoptera [PDF]

ZooKeys
Butterflies and moths (Lepidoptera) are one of the most commonly found insect groups in museum collections. Yet many specimens still lack digital data and few digitization workflows are available.
