Course Overview

This course introduces advanced concepts in impact mechanics as applied to biomechanics, focusing on theoretical foundations and practical applications. Students will gain an understanding of impact phenomena in engineering and biomechanics, with hands-on experience using ABAQUS for dynamic explicit simulations of human anatomical structures under impact loads.

The course covers impact mechanics theory (including rigid body impacts, wave propagation, and deformation of bodies), and provides an introduction to computational tools, specifically ABAQUS, to model and simulate impact events on biological tissues such as bones and soft tissues.

Learning Objectives

By the end of this course, students will be able to:

1. Theoretical Foundations

   • Understand core principles of impact mechanics.
   • Apply impact mechanics to biomechanical problems, including rigid body impacts and material deformation under impact loads.
   • Analyze the role of material properties in impact behavior.

2. Computational Modeling

   • Use ABAQUS to develop and simulate impact models for human anatomical structures.
   • Set up and analyze dynamic explicit simulations in ABAQUS.
   • Implement material models, including failure criteria, for simulating biological tissues under impact.

3. Biomechanical Applications

   • Apply theoretical and computational concepts to real-world biomechanical problems, such as simulating fractures or soft tissue injuries from impact events.
   • Interpret simulation results to assess injury risks and mechanical behavior of biological systems.

4. Problem-Solving Skills

   • Design impact scenarios with appropriate material properties, boundary conditions, and loading conditions in ABAQUS.
   • Analyze the results from simulations, interpret the impact of different conditions, and generate technical reports.
