Truss analysis using Abaqus software and Analytical solution

Project Overview

This Abaqus tutorial is designed to help you understand how to analyze a truss structure using the Abaqus software and the Analytical Solution.

In this example, the deflection of point E is calculated using the Abaqus software and the Analytical Solution. The results obtained from both methods are then compared with each other.

Problem Description

In this problem, a truss structure made of Aluminum is analyzed. A 40 kN force is applied to point E, and the resulting deflection of this point is investigated.

The truss is modeled in the Abaqus software, and the deflection of point E is obtained from the numerical analysis. The same problem is also investigated using the Analytical Solution in order to compare the results.

Analytical Solution

First, the deflection of point E is calculated using the Analytical Solution. This result is then used as a reference for comparison with the Abaqus result.

Abaqus Simulation

Next, the same truss structure is modeled and analyzed using the Abaqus software. The deflection of point E is obtained from the Abaqus results.

The deflection of point E obtained from the Abaqus software is equal to 16.2748 mm.

Comparison of Deflection Results

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

As observed, the results obtained from Abaqus are exactly the same as those obtained from the analytical solution.

Strain Energy of the Truss

In addition to calculating the deflection of point E, the strain energy of the whole truss is calculated using the Abaqus software. The obtained result is then compared with the corresponding result from the Analytical Solution.

The strain energy obtained from Abaqus is compared with the corresponding value obtained from the Analytical Solution. This comparison provides another way to evaluate the agreement between the numerical and analytical results.
