Energy dissipation in copper during VHCF loading

, 2011
This communication is dedicated to the presentation of an experimental setup developed to estimate the energy dissipated during high cycle fatigue tests (VHCF). VHCF tests are performed at very low stress ranges, generally under the conventional fatigue strength.

Automation in Strain and Temperature Control on VHCF with an Ultrasonic Testing Facility [PDF]

, 2014
Increased safety and reliability in mechanical components has become a subject of prime importance in recent years. Therefore, a proper understanding of damage and fracture mechanics in materials and components designed to withstand very high cycle fatigue (VHCF) loadings is extremely important nowadays.

Experimental Investigation of VHCF of Polymer Composites: Two Alternative Approaches^* [PDF]

Materials Testing, 2012
Abstract The need for reliable fatigue predictions arises with an increasing application of fibre-reinforced composites in primary light-weight structures with intended service times of up to 30 years. Only few data about very high cycle fatigue (VHCF) of polymer composites are available, because VHCF testing is rather challenging due to

Surface or Internal Fatigue Crack Initiation during VHCF of Tempered Martensitic and Bainitic Steels: Microstructure and Frequency/Strain Rate Dependency

Metals, 2022
By means of comparing the VHCF response of heat-treated alloy steel, several factors governing the transition from surface (type I) to internal (type II) VHCF failure, and, in the case of internal inclusion and non-inclusion type II VHCF failure, are ...

Cyclic deformation behavior of a medium carbon steel in the VHCF regime

Procedia Engineering, 2010
AbstractAt the Institute of Materials Science and Engineering an ultrasonic testing facility (UTF) for the fatigue assessment in the very high cycle fatigue (VHCF) regime was developed. The UTF allows to control the test and to measure process parameters like generator power and specimen temperature.

Self-Regulating Sodium-Ion Battery Materials: From Phase Reconstruction to Functional Activation. [PDF]

Adv Mater
Self‐regulating sodium‐ion batteries hinge on programmable phase behavior in layered oxides, interphases that renew without growth, and electrolytes that steer solvation and chemistry. This review distills mechanisms into design rules that span composition, site and entropy tuning, and self‐buffering anodes, linking operando evidence to choices and ...

Ionic Liquid-Based Electrolyte with Multiple Hydrogen Bonding Network Enabling High-Voltage Stable Proton Batteries Across Wide Temperature Range. [PDF]

Adv Sci (Weinh)
An ionic liquid electrolyte with multilane hydrogen‐bond interactions is designed for stable, high‐voltage proton storage. Such enhanced hydrogen bond imparts rapid and stable electrochemical proton storage with a high operating voltage of 2 V. A symmetric full proton battery using the electrolyte achieves a maximum energy density of 87.5 Wh kg−1 and a
