Pure torsional yielding damper under cyclic loading Abaqus

Product Overview

In this example, we intend to simulate a Pure Torsional Yielding Damper under cyclic loading in the Abaqus software.

The numerical model is developed to investigate the cyclic behavior, deformation, and hysteretic response of the pure torsional yielding damper.

Laboratory and Abaqus Models

As you observe in the picture, the laboratory model is shown on the right, while the model simulated in the Abaqus software is shown on the left.

Model Components

As you observe in the picture, this model is composed of a Pipe Damper, Lever, Link, Lower Part, and Upper Part.

Hinges

In this model, the links, levers, upper part, and lower part have all been connected together using hinges.

A total of 12 hinges are used to connect the different parts of the model.

Cyclic Loading

In this problem, cyclic loading is applied to the model to investigate the hysteretic behavior of the pure torsional yielding damper.

The cyclic loading history is defined in Abaqus using the corresponding amplitude data.

Force-Displacement Hysteresis Diagram

After applying the cyclic loading, the Force-Displacement hysteresis diagram is obtained from the Abaqus results.

As you observe in the picture, the Force-Displacement hysteresis diagram obtained from the Abaqus software is compared with the experimental results.

Deformation Comparison

The deformation obtained from the Abaqus software is compared with the deformation observed in the experimental test.

As you observe in the pictures, the deformation obtained from the numerical model is compared with the experimental results.

Deformation Under Cyclic Loading

The deformation of the model under cyclic loading can be observed in the following picture.

Validation

This project has been validated, which means that the results obtained from the Abaqus software are similar to the results reported in the reference article.

In other words, this project is based on the reference article, and the numerical model has been developed to reproduce the experimental behavior of the pure torsional yielding damper under cyclic loading.
