Closed-form critical earthquake response of elastic-plastic structures on compliant ground under near-fault ground motions

open access: yesFrontiers in Built Environment, 2016
The double impulse is introduced as a substitute of the fling-step near-fault ground motion. A closed-form solution of the elastic-plastic response of a structure on compliant (flexible) ground by the ‘critical double impulse’ is derived for the first ...

High resolution incremental stress testing of crushable granular materials [PDF]

open access: yesE3S Web of Conferences, 2019
The incremental behaviour of crushable sands is investigated by means of a Discrete Element Method (DEM) based analogue. The DEM sample is subjected to a comprehensive set of small stress perturbations in the triaxial plane in order to identify the basic

Elastic-Plastic Response of Pipe under Collision

open access: yesJournal of the Society of Naval Architects of Japan, 1987
It is necessary to have a comprehensive understanding of the structural response under collision to design offshore structures against possible accidents. A general procedure based on theoretical analyses to classify the elastic responses of frame structures under collision has been reported by the authors.

A fully implicit multi-axial solution strategy for direct ratchet boundary evaluation : theoretical development [PDF]

open access: yes, 2012
Ensuring sufficient safety against ratchet is a fundamental requirement in pressure vessel design. Determining the ratchet boundary can prove difficult and computationally expensive when using a full elastic-plastic finite element analysis and a number ...

Critical Earthquake Response of 2DOF Elastic-Perfectly Plastic Model Under Multiple Impulse as Substitute for Long-Duration Earthquake Ground Motions

open access: yesFrontiers in Built Environment, 2019
An equi-spaced consecutive impulse input is treated as a simplified representative for a long-duration earthquake ground motion. The key property of such input can be captured approximately by using harmonic waves.

Comprehensive Review of Optimal and Smart Design of Nonlinear Building Structures With and Without Passive Dampers Subjected to Earthquake Loading

open access: yesFrontiers in Built Environment, 2021
The optimal and smart design of nonlinear building structures with and without passive dampers subjected to earthquake loading is of great concern in the structural design of building structures.

Performance characteristics of recycled concrete aggregate as an unbound pavement material

open access: yesHeliyon, 2019
Use of recycled concrete aggregates (RCA) as a pavement material is one of the most sustainable engineering applications for the pavement industry. Investigation on the performance characteristics of RCA, such as elastic and plastic deformations of RCA ...

Bending deformation driven by molecular rotation

open access: yesPhysical Review Research, 2023
In recent years, certain molecular crystals have been reported to possess surprising flexibility by undergoing significant elastic or plastic deformation in response to mechanical loads. However, despite this experimental evidence, there currently exists
