Temporal change in seismic velocity associated with an offshore M W 5.9 Off-Mie earthquake in the Nankai subduction zone from ambient noise cross-correlation

Progress in Earth and Planetary Science, 2018
The Nankai subduction zone off the Kii Peninsula, Japan, has a large potential to generate megathrust earthquakes in the near future. To investigate the temporal variation of stress or strain in the Nankai subduction zone, we estimated the temporal ...

Limiting the effects of earthquakes on gravitational-wave interferometers

, 2017
Ground-based gravitational wave interferometers such as the Laser Interferometer Gravitational-wave Observatory (LIGO) are susceptible to high-magnitude teleseismic events, which can interrupt their operation in science mode and significantly reduce the ...

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.

Seismic dynamic response analysis for tunnels considering coseismic displacement

Yantu gongcheng xuebao
Fault dislocation is a form of dynamic impact load that induces permanent deformation of the stratum in the vicinity of the fault. Based on the finite-fault source and crustal velocity model, coseismic displacement is computed according to the layered ...

Production of MgO/TiC Composites From MgO‐C Recyclates Using Spark Plasma Sintering

Advanced Engineering Materials, EarlyView.
Using the spark plasma sintering technique, MgO/TiC composites are manufactured from recycled MgO‐C refractories stemming from the steel production that were mixed with titanium powder. This article shows, how the size of the Ti grains and their distribution in the powder mixture affect the local carbon concentration in TiC.

Evaluation of Plasticity and Creep Parameters From Tensile Stress–Strain Data for a Range of Strain Rates

Advanced Engineering Materials, EarlyView.
This plot compares experimental tensile stress–strain curves (with 4 different strain rates) and corresponding modelled curves (obtained using the optimised sets of Voce and Miller–Norton parameter values shown). The inferred M‐N values, characterizing the creep, are very similar to those obtained via conventional creep testing.

Characteristics of peak ground motions and nonlinear site response during the 2024 Mw 7.5 Noto Peninsula earthquake

Earth, Planets and Space
The 2024 Mw 7.5 Noto Peninsula earthquake was the largest inland earthquake recorded by dense K-NET and KiK-net strong-motion seismographs in Japan after their establishment in the second half of the 1990s.

Changes in Lower-Extremity Gait Biomechanics Following High-Cadence Cycling

Sports
We sought to investigate the lower-extremity biomechanics underlying increased gait velocity following high-cadence cycling. Ground reaction forces (GRF) and lower-extremity kinematics and kinetics were recorded as 15 healthy adults walked at a self ...

Preliminary study of inphase gusts and moment force wind loads over the first 150 meters at KSC, Florida [PDF]

A mathematical/statistical analysis of inphase gusts and wind velocity moment forces over the first 150 m at the Kennedy Space Center (KSC) is presented. The wind velocity profile data were acquired at the KSC 150 m ground wind tower.
