Plane stress to a single element- help

Click For Summary
SUMMARY

The discussion focuses on applying plane stress conditions to a single element in a finite element analysis (FEA) context. The user has constrained nodes 1 and 2 in the horizontal (x) direction, nodes 1 and 3 in the vertical (y) direction, and all three nodes in the z direction, ensuring a constant stress and strain throughout the element. The user seeks validation on the correctness of the stress distribution results and the application of boundary conditions. The consensus indicates that the boundary conditions are appropriately applied for a plane stress scenario.

PREREQUISITES
  • Understanding of finite element analysis (FEA)
  • Knowledge of plane stress conditions in structural mechanics
  • Familiarity with boundary condition application in FEA software
  • Basic concepts of stress and strain in materials
NEXT STEPS
  • Research the implementation of plane stress conditions in ANSYS or ABAQUS
  • Learn about the effects of boundary conditions on stress distribution in FEA
  • Explore validation techniques for FEA results
  • Study the principles of stress and strain transformation in materials
USEFUL FOR

Structural engineers, finite element analysts, and students studying mechanics of materials who are looking to deepen their understanding of plane stress applications and boundary condition implementations in FEA.

Dear All,
I just have a single element, I need to apply a plane stress condition as in the attached image.

For the boundary conditions;
• I have constrained the nodes 1 and 2 in the horizontal (x) direction
• I have constrained the nodes 1 and 3 in the vertical (Y) direction
• I have constrained nodes 1,2,3 in z (perpendicular) direction.
• I have got a constant stress and strain throughout the element

Are the results i.e. stress distribution correct qualitatively? Have I applied the boundary conditions correctly?

Please can anyone advise?
