Polymers are a class of materials that are composed of long chains of repeating units. They are used in a wide variety of applications, including packaging, construction, and automotive parts. The mechanical behavior of polymers is important for understanding how they will perform in these applications.

This book provides a comprehensive overview of the mechanical behavior of polymers. It covers a wide range of topics, including the basic concepts of polymer mechanics, the different types of deformation and fracture mechanisms, and the factors that influence these mechanisms. The book also includes a number of case studies that illustrate the application of these concepts to real-world problems.

Basic Concepts of Polymer Mechanics

The basic concepts of polymer mechanics are essential for understanding the deformation and fracture behavior of polymers. These concepts include:

• Stress: Stress is a measure of the force applied to a material per unit area.
• Strain: Strain is a measure of the deformation of a material.
• Elastic modulus: The elastic modulus is a measure of the stiffness of a material.
• Yield strength: The yield strength is the stress at which a material begins to deform plastically.
• Tensile strength: The tensile strength is the stress at which a material breaks.

Types of Deformation and Fracture Mechanisms

There are a number of different types of deformation and fracture mechanisms that can occur in polymers. These mechanisms include:

• Elastic deformation: Elastic deformation is a reversible deformation that occurs when a material is stressed below its yield strength.
• Plastic deformation: Plastic deformation is an irreversible deformation that occurs when a material is stressed above its yield strength.
• Fracture: Fracture is the failure of a material under stress.

Factors Influencing Deformation and Fracture Mechanisms

The deformation and fracture behavior of polymers is influenced by a number of factors, including:

• Temperature: Temperature can affect the mechanical properties of polymers. For example, polymers are typically more ductile at higher temperatures.
• Strain rate: Strain rate is the rate at which a material is deformed. Strain rate can affect the mechanical properties of polymers. For example, polymers are typically more brittle at higher strain rates.
• Environmental conditions: Environmental conditions, such as humidity and exposure to chemicals, can affect the mechanical properties of polymers.

Case Studies

The book includes a number of case studies that illustrate the application of the concepts of polymer mechanics to real-world problems. These case studies include:

• The use of polymers in packaging
• The use of polymers in construction
• The use of polymers in automotive parts
