Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Comprehensive study of the off-axis mechanical behaviors of a Polytetrafluoroethylene‐ coated fabric after 23 Years of service at Shanghai stadium

Journal of Industrial Textiles
Coated fabrics can experience mechanical performance degradation due to environmental factors and long-term stress during service. Hence, studying the mechanical behaviors of these materials after aging is crucial.

Influence of TESPT on Tensile and Tear Strengths of Vulcanized Silica-filled Natural Rubbe

ASEAN Journal on Science and Technology for Development, 2018
The effectof coupling agent on tensile and tear strengthsof vulcanized NR filledwith 50 pphr of precipitated silica (VN3) was investgated. The amount of coupling agent was varied from 0,1,2,3,4,5 to 8 pphr. In the absence of coupling agent bis[3-(triethoxysilyl)propyl] tetrasulphide (TESPT), the tensile strengthof silica-fille vulcanized NR was lower ...

Slip Localization Intensification Mediated by Grain Boundary Sliding in a Polycrystalline Nickel‐Based Superalloy

Advanced Engineering Materials, EarlyView.
The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

CORRELATION BETWEEN TENSILE STRENGTH AND TEAR RESISTANCE OF PERFORATED E FLUTE CORRUGATED BOARD [PDF]

, 2021
Resistance measurements calculated from Elmendorf tests provide valuable insight into durability and lifespan characteristics of observed material. However, Elmendorf method is suitable for testing tear resistance of paper and paperboard but not corrugated board.
