Learn about the molecular weight, degree of polymerization, crystallinity, and spherulites of polymers, and how they affect their physical and mechanical properties. This chapter is from Biosurfaces: A Materials Science and Engineering Perspective, edited by Kantesh Balani and others.
The mechanical properties of a polymer involve its behavior under stress. These properties tell a polymer scientist or engineer many of the things he or she needs to know when considering how a polymer can be used.
Learn how molecular weight, crystallinity, and other factors affect the mechanical properties of polymers, such as yield stress, modulus, and impact resistance. See examples of different types of polymers and their physical appearance, stiffness, and toughness.
Localized Deformation in Polymers. 1. Crazing (dilational deformation) 2. Shear banding (constant volume deformation) Crazes (for glassy polymers, micronecks for semiXLine polymers) Orient perpendicular to principal tensile stress.
22 lut 2013 · This chapter talks about structure of polymer chains, and mechanical properties of polymers and polymer composites. Properties of polymers, as in the case of any chemical compound, are highly depende...
1 sty 2020 · The basic mechanical properties of polymeric materials are tensile strength, elongation at break, Young’s modulus, toughness, and viscoelasticity. The tensile strength of a polymeric material is generally defined in terms of the stress required for breaking the material.
