MusclePy is a Python package for structural analysis that focuses on the design, analysis, and optimization of tensegrity, tension-based, and truss-like structures.

MusclePy

Overview

MusclePy is a Python package for structural analysis that focuses on the design, analysis, and optimization of tensegrity, tension-based, and truss-like structures.

Features

• Finite Element Modeling: Create and manipulate structural models with PyNodes, PyElements, and PyTruss
• Singular Value Decomposition (SVD): Analyze equilibrium matrices to identify mechanisms and self-stress modes
• Self-stress Modes: Localize and sort self-stress modes in tensegrity structures
• Displacement Methods: Solve structural problems using linear and nonlinear displacement methods
• Dynamic Relaxation: Form-finding and analysis using dynamic relaxation techniques
• Dynamic Modal Analysis: Compute natural frequencies and mode shapes of vibrations of structures

Installation

pip install musclepy

Quick Start

import musclepy as mp

# Create a simple structure
nodes = mp.PyNodes()
elements = mp.PyElements(nodes)
truss = mp.PyTruss(nodes, elements)

# Add nodes and elements
# ...

# Compute SVD
results = mp.main_singular_value_decomposition(truss)

# Localize self-stress modes
localized_modes = mp.localize_self_stress_modes(results.self_stress_modes)
