Thick-Wall Pipe Analysis

This project demonstrates the structural analysis of a Thick-Wall Pipe using OpenSeesPy. The model comprises 4 triangular elements and 6 nodes, simulating a 2D plane strain system under static loading.

Project Overview

1. Nodes and Elements:

   • 6 nodes are defined to represent the geometry.
   • 4 triangular elements (Tri31) model the plane-strain behavior.

2. Material Properties:

   • Elastic isotropic material with:
     • Young's Modulus: 100,000 kN/m²
     • Poisson's Ratio: 0.25

3. Boundary Conditions:

   • 4 sliding supports restrict movement in one direction.

4. Loading:

   • Static loads applied on nodes to simulate external forces.

5. Analysis:

   • Linear static analysis calculates displacements at nodes.

How to Run

1.Dependencies

• Install the required libraries:

pip install openseespy openseespy.postprocessing

2.Execution

Run the script using Python:

python main.py

Outputs

1. Node Displacements:

The script prints the displacements (x and y) for all nodes.

Sample Output:

1 numaralı düğüm x= 0.0 mm  -  y= 0.0 mm
2 numaralı düğüm x= 0.1 mm  -  y= -0.2 mm
...

2. Model Visualization:

The model is plotted with nodes and elements for verification.

Visualization

Model Rendering

The nodes and elements are visualized as a schematic diagram:

• Nodes are labeled.
• Triangular elements are displayed.
