Stress analysis of a beam using ANSYS Mechanical APDL

Published on 03 Jul 2021. Written by Gurudutt

Beams are descriptions of the building or civil engineering structural elements, but any structures such as motorized automobile frames, plane mechanisms, engine settings, and other or structural systems contain beam constructions that are intended to carry adjacent loads are analyzed

APDL stands for ANSYS Parametric Design Language.

ANSYS is a software setting for the implementation of structural, thermal, and electromagnetic analyses. Focuses on geometry creation and optimization, attaching existing geometry, setting up the finite element model, resolving, and revising results

Boolean Operations Boolean Operations (based on Boolean algebra) provide a means of combining sets of data using such logical operators as add, subtract, intersect, etc. There are Boolean operations available for volume, area, and line solid model entities.

 

Types of structural stress:  

• The five basic structural stresses to which aircraft are subject are:
• Tension: Apply a force to which tends to stretch it.
• Compression: It refers to the decrease in capacity.
• Torsion: It is the twisting of an object due to an applied torque
• Shear: It arises from the force vector component
• Bending: Object which bends on the application of force.

In the current project, stress analysis is done on beams on either the side. Load-carrying beams are then modeled and studied for further analysis.

Procedure:

• ANSYS Mechanical APDL
• Select Ansys Multiphysics
• Save the project and run
• Go to Ansys utility menu-clear and start new
• Go to file change the job name- enter a new job name.
• Go to Ansys main menu- Preferences Select – structural- ok
• Go to Preprocessor
• Select element type- Add/edit/delete- select the beam
• Select real constants-give the details such as thickness, area, a moment of inertia, etc
• Material properties- give details such as young’s modulus, Poisson's ratio, etc depending on the nature of the problem.
• Go to modeling- create the required geometry such as nodes element, area, volume by using the appropriate options
• Go to Generate- elements/nodes using mesh tool if necessary.
• Apply boundary conditions/loads
• Go to solve- current LS- click ok
• Go to general post processor- check results.
• Go to plot controls- select the animate option and see the results.
• Go to Main Menu- Time History- Postprocessor- Read Results- First Set
• Go to Utility Menu- Plot Controls
• Review Results- Enter the general postprocessor and read in the results.
• Main Menu- Time History- Postprocessor- Graph Variables, ‘’1st variable to graph” = 2
• Plot the results at control point as a function of time
• Plot the deformed shape.
