Abaqus CAE File: Stress Analysis of a Plate with Circular Hole

Stress concentration around holes is one of the fundamental topics in mechanical and structural engineering. Circular holes in plates are widely used in practical applications such as bolted joints, lightweight structures, aerospace components, and machine parts. This Abaqus CAE file provides a complete finite element model for analyzing the stress distribution around a circular hole under tensile loading.

In this example, a flat plate with a central circular hole is modeled using Abaqus/CAE under plane stress conditions. The plate is subjected to an applied tensile force on one side while the opposite side is constrained. Due to geometric symmetry, only one-quarter of the plate is modeled, reducing computational cost while maintaining accurate results.

The model demonstrates how to define symmetry boundary conditions, apply mechanical loads, generate an appropriate mesh, and evaluate stress concentration effects around the hole.
