Mechanical Behavior of Polymers: Stress, Strain, and Deformation

Plastics are ubiquitous in modern design, but their unique mechanical properties—unlike metals—require specialized knowledge for reliable engineering. This course provides a comprehensive, text-based foundation in polymer mechanics, enabling you to move beyond simple assumptions and understand the molecular and continuum principles governing material performance under stress. Upon completion, you will be equipped to analyze and predict the mechanical performance of polymeric components based on fundamental materials science. This knowledge is essential for preventing premature failure and optimizing design for long-term use. What you'll learn: * Understand the molecular structure of polymers and how it dictates macroscopic mechanical properties. * Apply principles of stress, strain, elastic deformation (Hookean and entropic), and thermal expansion. * Analyze time-dependent behavior using linear viscoelasticity models, including creep and stress relaxation. * Master the concepts of yield, ductility, and fracture mechanics specific to plastic materials. * Learn how processing, temperature, and environmental factors influence the long-term reliability and failure modes of components. * Practice interpreting material data sheets and selecting appropriate polymers for structural and dynamic applications. The course begins with foundational polymer chemistry and continuum mechanics, progresses through elasticity and time-dependent viscoelastic models, and concludes with practical applications in yield and fracture analysis. This course is designed for absolute beginners in materials science, mechanical engineering, and product design who need a solid foundation in the behavior of polymeric materials. No prior knowledge of advanced mechanics or polymer chemistry is required. Start building reliable plastic components based on sound mechanical principles today.
