Random Dynamics of a Bar System

RandBar: Random Dynamics of a Bar System is a powerful Matlab tool designed to simulate the nonlinear stochastic dynamics of a bar structural system with attached discrete elements. The code is developed with an educational approach, making it user-friendly and intuitive.

Table of Contents

Overview

RandBar was developed to conduct stochastic simulations of a bar structural system with attached discrete elements. The results have been published in a peer-reviewed journal:

  • A. Cunha Jr, R. Sampaio, On the nonlinear stochastic dynamics of a continuous system with discrete attached elements, Applied Mathematical Modelling, 39, pp. 809-819, 2015. DOI

Features

  • Simulates nonlinear stochastic dynamics of bar systems
  • Intuitive Matlab implementation
  • Educationally styled code for easy understanding

Usage

To get started with RandBar, follow these steps:

  1. Clone the repository: 
    git clone https://github.com/americocunhajr/RandBar.git
  2. Navigate to the code directory: 
    cd RandBar/RandBar-1.0
  3. Execute: 
    main__randbar_fixed_mass_spring__MC

Documentation

The routines in RandBar are thoroughly commented to explain their functionality. Each routine includes a description of its purpose, as well as inputs and outputs.
