Questions about polymers
- How does the structure of UHMwPE change if it is torn in 2 directions?
Please tell me how the structure of UHMwPE changes if it is torn in 2 directions.
UMHwPE is ultra high molecular weight polyethylene, a polymer used in making prosthetic
joint replacements. It's important to understand how and why the polymer fractures under stress to improve the design of these devices.
