Change in length of the rod due to the axial force using Abaqus software and Strength of Materials

Project Overview

This Abaqus tutorial focuses on calculating the change in length of the rods due to an axial force using the Abaqus software and the Strength of Materials.

In this training, we first solve the problem using the Abaqus software. Then, the same problem is solved using the principles of Strength of Materials. Finally, the results obtained from Abaqus are compared with those obtained from the Strength of Materials.

Problem Description

In this problem, two bars made of steel and aluminum are connected together. A force of 20 kN is applied to the aluminum bar.

The main objective of this problem is to calculate the displacement of points B and C and compare the results obtained from Abaqus with the results obtained using the Strength of Materials.

Abaqus Simulation

The problem is first modeled and analyzed using the Abaqus software. The axial force is applied to the aluminum bar, and the resulting displacements are obtained from the Abaqus analysis.

The displacement of point B is obtained from the Abaqus results.

The displacement of point C is also obtained from the Abaqus results.

Strength of Materials Solution

In the next step, the same problem is solved using the Strength of Materials. The displacement of the specified points is calculated based on the axial deformation of the connected bars.

Comparison of Results

The results obtained from the Abaqus software are compared with those obtained using the Strength of Materials.

As observed from the results, the results obtained from the Abaqus software are quite equal to those obtained using the Strength of Materials.
