__Sample Project: Finite Element Analysis of a 2D Truss__

In order to conduct a basic 2D truss finite element analysis with Python, an explicit instance is offered by us:

**Step 1: Import Required Libraries**

import numpy as np

import matplotlib.pyplot as plt

**Step 2: Specify the Truss Structure**

# Node coordinates (x, y)

nodes = np.array([[0, 0], [1, 0], [1, 1], [2, 1], [2, 0], [3, 0]])

# Element connectivity (start node, end node)

elements = np.array([[0, 1], [1, 2], [1, 4], [2, 3], [2, 4], [3, 4], [4, 5]])

# Element properties (Young’s modulus, area)

E = 210e9 # Young’s modulus in Pascals

A = 1e-4 # Cross-sectional area in square meters

**Step 3: Define Functions for FEA**

def length_and_cosines(node1, node2):

delta = node2 – node1

L = np.linalg.norm(delta)

cos = delta[0] / L

sin = delta[1] / L

return L, cos, sin

def element_stiffness_matrix(L, cos, sin, E, A):

k = (E * A / L) * np.array([[cos**2, cos*sin, -cos**2, -cos*sin],

[cos*sin, sin**2, -cos*sin, -sin**2],

[-cos**2, -cos*sin, cos**2, cos*sin],

[-cos*sin, -sin**2, cos*sin, sin**2]])

return k

**Step 4: Set the Global Stiffness Matrix**

# Number of nodes and degrees of freedom (DOF)

num_nodes = nodes.shape[0]

dof = 2 * num_nodes

# Initialize global stiffness matrix

K = np.zeros((dof, dof))

# Assemble global stiffness matrix

for element in elements:

node1, node2 = element

L, cos, sin = length_and_cosines(nodes[node1], nodes[node2])

k = element_stiffness_matrix(L, cos, sin, E, A)

dof_indices = np.array([2*node1, 2*node1+1, 2*node2, 2*node2+1])

for i in range(4):

for j in range(4):

K[dof_indices[i], dof_indices[j]] += k[i, j]

**Step 5: Implement Boundary Conditions and Solve**

# Boundary conditions (fixed nodes)

fixed_nodes = [0, 5]

free_dof = np.array([i for i in range(dof) if i//2 not in fixed_nodes])

# Load vector (applied loads)

F = np.zeros(dof)

F[3] = -1000 # Apply a downward force of 1000 N at node 2

# Solve for displacements

K_ff = K[np.ix_(free_dof, free_dof)]

F_f = F[free_dof]

U_f = np.linalg.solve(K_ff, F_f)

# Full displacement vector

U = np.zeros(dof)

U[free_dof] = U_f

**Step 6: Post-Processing and Visualization**

# Extract displacements

displacements = U.reshape(num_nodes, 2)

# Deformed shape

scale_factor = 1e3 # Scale factor for visualization

deformed_nodes = nodes + scale_factor * displacements

# Plot original and deformed truss

plt.figure()

for element in elements:

node1, node2 = element

plt.plot(nodes[[node1, node2], 0], nodes[[node1, node2], 1], ‘bo-‘)

plt.plot(deformed_nodes[[node1, node2], 0], deformed_nodes[[node1, node2], 1], ‘ro–‘)

plt.xlabel(‘X Coordinate (m)’)

plt.ylabel(‘Y Coordinate (m)’)

plt.title(‘Original and Deformed Truss’)

plt.legend([‘Original’, ‘Deformed’])

plt.grid(True)

plt.axis(‘equal’)

plt.show()
