Feasibility study of full-scale elastic-plastic seismic response analysis of nuclear power plant

Mechanical Engineering Journal, 2019
A finite element elastic-plastic seismic response analysis using a full-scale integrated model of Unit 1 of the Fukushima-Daiichi Nuclear Power Plant, which was subjected to the 2011 off the Pacific coast of Tohoku Earthquake, is performed using the K ...

Critical Response of Multi-Story Damped Bilinear Hysteretic Shear Building Under Multi Impulse as Representative of Long-Period, Long-Duration Earthquake Ground Motions

Frontiers in Built Environment, 2020
The critical response is investigated for a multi-story damped bilinear hysteretic shear building model under a multi impulse as a representative of long-period, long-duration earthquake ground motions. The critical response for an elastic–plastic single-

Elastic-plastic response of mild steel beams to impulse loads [PDF]

, 1977
The elastic-plastic response of 1018 steel beams was examined experimentally and analytically. Simply supported beams were loaded with half-sine distributed, short-duration magnetic pressure pulses and the response monitored with a streak camera and strain gages.

Elastoplastic Analysis of Circular Opening Based on a New Strain-Softening Constitutive Model and Its Engineering Application in Hydraulic Fracturing

Advances in Civil Engineering, 2018
Constitutive effect is extremely important for the research of the mechanical behavior of surrounding rock in hydraulic fracturing engineering. In this paper, based on the triaxial test results, a new elastic-peak plastic-softening-fracture constitutive ...

Critical input and response of elastic-plastic structures under long-duration earthquake ground motions

Frontiers in Built Environment, 2015
The multiple impulse input is introduced as a substitute of the long-duration earthquake ground motion, mostly expressed in terms of harmonic waves, and a closed-form solution is derived of the elastic-plastic response of a single-degree-of-freedom ...

Critical Response of Single-Degree-of-Freedom Damped Bilinear Hysteretic System under Double Impulse As Substitute for Near-Fault Ground Motion

Frontiers in Built Environment, 2018
A double impulse input is used as a substitute for near-fault earthquake ground motions. An explicit expression is derived on the maximum elastic–plastic response of a single-degree-of-freedom damped structure with bilinear hysteresis under the “critical

Study on the mechanical response characteristics of sandstone under elasticity plasticity and full path unloading after peak stress

Scientific Reports
When underground tunnels in coal mines traverse geological structurally abnormal zones (faults, collapse columns, fractured zones, etc.), excavation-induced unloading leads to instability and failure of the engineering rock mass. Rock masses in fractured

Questioning size effects as predicted by strain gradient plasticity

Journal of the Mechanical Behavior of Materials, 2013
The analytical solution of the elastic-plastic response of a two-phase laminate microstructure subjected to periodic simple shear loading conditions is derived considering strain gradient and micromorphic plasticity models successively. One phase remains
