Experimental Characterization and Constitutive Modeling of the Effect of Prior Inelastic Strain on the Viscoplastic Behavior of AD730 at 700 °C

Advanced Engineering Materials, EarlyView.
This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

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 ...

Investigation of Ground Vibration of Full-Stone Foundation under Dynamic Compaction

Shock and Vibration, 2019
This study focuses on the ground vibration of a full-stone foundation treatment project. The single-point dynamic compaction test was performed using a tamping machine at an energy level of 3200 kN·m. Time-history curves of ground vibration velocity were

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

Advanced Engineering Materials, EarlyView.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

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.

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐

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 ...

Kinetic comparison of the power development between the hang clean, jump shrug and high pull

, 2012
PURPOSE: To compare the kinetics of the hang clean (HC), jump shrug (JS), and high pull (HP) when performed at different relative loads. METHODS: Seventeen men with at least 2 years of training experience with the HC performed 3 repetitions each of the ...
