Polymer yield calculation
WebPolymer Yielding: (Based on I. M. Ward's "Mechanical Properties of Polymers") Yielding in polymers is strongly temperature and strain-rate dependent. By choosing a standard test rate it is possible to adopt yield and failure functions such as the Von Mises Criterion for … WebIncreasing the polymer content only slightly above this level to 0.5% yielded materials with frequency-independent moduli, dramatically increased strain-to-yield, and increased yield …
