Uniaxial elastic-plastic wave propagation [PDF]

, 2018
This article considers the uniaxial elastic-plastic response of a solid slab subject to a velocity applied to one boundary, over time scales on which both elastic and plastic waves can propagate. We briefly describe a simple model in which the amplitudes

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-

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.

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 ...

3D simulation of dry friction of metal-based composites [PDF]

EPJ Web of Conferences, 2019
A numerical 3D model of friction at mesoscale of the contact patch between steel samples and composite steel samples with carbon nanoinclusions has been developed based on the movable cellular automaton method.

A direct method for the evaluation of lower and upper bound ratchet limits [PDF]

, 2011
The calculation of the ratchet limit is often vital for the assessment of the design and integrity of components which are subject to cyclic loading. This work describes the addition of a lower bound calculation to the existing Linear Matching Method ...

Identification of viscoplastic parameters and characterization of Lüders behaviour using digital image correlation and the virtual fields method [PDF]

, 2008
In this study, tensile loading experiments are performed on notched steel bars at an average applied strain rate of 1s-1. Displacement fields are measured across the specimen by coupling digital image correlation (DIC) with imaging using high speed CCD ...
