This text investigates the fundamental mechanisms governing the initiation and propagation of cracks within polymeric materials. E. H. Andrews, a recognized authority in polymer physics, synthesizes experimental observations with theoretical fracture mechanics to explain how molecular structure influences macroscopic failure. The book provides a rigorous framework for understanding the energy balance and stress distribution required for material separation in various polymer types.

Experts in materials science identify this work as a foundational text for understanding the intersection of polymer physics and fracture mechanics. Readers frequently note the technical density of the prose, which requires a strong background in mechanics and thermodynamics to fully comprehend the presented arguments.
