A New Unified Solution for Circular Opening considering Different Strength Criteria and the Postpeak Elastic Strain Form

Advances in Civil Engineering, 2020
The strength criterion is an extremely important basis for evaluating the stability of surrounding rock and optimizing the support pressure design. In this paper, nine different strength criteria are summarized and simplified based on the reasonable ...

General Dynamic Collapse Criterion for Elastic–Plastic Structures Under Double Impulse as Substitute of Near-Fault Ground Motion

Frontiers in Built Environment, 2020
A dynamic collapse criterion for elastic–plastic structures under near-fault ground motions is derived analytically by approximately transforming near-fault ground motions into double impulse and using an energy balance law.

Helical single-walled carbon nanotubes under mechanical and electrostatic loading

Carbon Trends, 2022
Here, we characterize the axial response of helical single-walled carbon nanotubes (HSWCNTs) to mechanical and electrostatic loads, separately. The study considers low-pitch (closed) and high-pitch (open) HSWCNTs of different number of turns in their ...

Learning the non-proportional multiaxial elastic–plastic response of an aluminium alloy with neural networks

Materials & Design
We present a surrogate model for the elastic–plastic response of an aluminium alloy, based on simple neural networks trained on measurements taken in tension–torsion and compression-torsion experiments.

Critical earthquake response of elastic-plastic structures under near-fault ground motions (Part 2: Forward-directivity input)

Frontiers in Built Environment, 2015
The triple impulse input is used as a simplified version of the forward-directivity near-fault ground motion and a closed-form solution of the elastic-plastic response of a structure by this triple input is obtained.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

Advanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

A plastic load criterion for inelastic design by analysis [PDF]

, 2006
The allowable plastic load in pressure vessel design by analysis is determined by applying a graphical construction to a characteristic load-deformation plot of the collapse behavior of the vessel.

Critical earthquake response of a SDOF elastic‐perfectly plastic model with viscous damping under double impulse as a substitute for near‐fault ground motion

Japan Architectural Review, 2018
The double‐impulse input is introduced as a substitute for the fling‐step near‐fault ground motion, and a closed‐form solution for the approximate elastic‐plastic response of a structure with viscous damping under the “critical double impulse” is derived.
