Buckling of a honeycomb damper under cyclic loading Abaqus

Product Overview

In this example, we intend to simulate the buckling of a honeycomb damper under cyclic loading in the Abaqus software.

Actually, the honeycomb damper is a metallic damper that is investigated under cyclic loading to evaluate its structural response and buckling behavior.

Laboratory Sample

In this picture, you can observe the laboratory sample of the honeycomb damper used in the experimental study.

Cyclic Loading

In this analysis, cyclic loading is applied to the honeycomb damper to investigate its behavior under repeated loading and unloading cycles.

The loading history is defined in Abaqus according to the loading protocol used in the experimental study.

Buckling of the Honeycomb Damper

The main objective of this project is to investigate the buckling behavior of the honeycomb damper under cyclic loading.

The deformation and buckling response obtained from the Abaqus model can be used to evaluate the behavior of the metallic damper during cyclic loading.

Force-Drift Hysteresis Diagram

After performing the cyclic analysis, the Drift-Force hysteresis diagram is obtained from the Abaqus results.

The hysteresis diagram is then compared with the results obtained from the experimental sample.

Comparison of Abaqus and Experimental Results

In this picture, the force-drift hysteresis diagram obtained from the Abaqus software is compared with the results obtained from the experimental sample.

This comparison is used to evaluate the accuracy of the numerical model and its ability to reproduce the experimental response of the honeycomb damper.

Validation

This project has been validated, which means that the results obtained from the Abaqus software are similar to the results reported in the 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 honeycomb damper under cyclic loading.
