Calculation of vertical deflection using Abaqus software and Analytical Solution

Project Overview

This Abaqus tutorial is available is designed to help you understand how to calculate the vertical deflection of a model using the Abaqus software and the Analytical Solution.

In this example, the vertical deflection of point A is first calculated using the Analytical Solution. Then, the same problem is modeled and analyzed using the Abaqus software. Finally, the results obtained from Abaqus are compared with those obtained from the Analytical Solution.

Problem Description

As shown in the figure, the model consists of a lever AB and a rod BC. A force of 450 N is applied to point A.

The length of the lever AB is 500 mm, while the length of the rod BC is 600 mm.

The main objective of this problem is to determine the vertical deflection of point A using both the Analytical Solution and the Abaqus software, and then compare the results obtained from the two methods.

Analytical Solution

First, the vertical deflection of point A is calculated using the Analytical Solution.

The vertical deflection obtained from the Analytical Solution is equal to 59.82 mm.

Abaqus Simulation

Next, the same model is created in the Abaqus software. A force of 450 N is applied to point A, and the vertical deflection of point A is obtained from the Abaqus results.

The vertical deflection obtained from the Abaqus software is equal to 60 mm.

Comparison of Results

Finally, the vertical deflection of point A obtained from the Abaqus software is compared with the result obtained from the Analytical Solution.

The Analytical Solution gives a vertical deflection of 59.82 mm, while the result obtained from Abaqus is 60 mm.

As observed, the results obtained from the Abaqus software are precisely concordant with those obtained from the Analytical Solution.
