The 400× stiffness gap between 316L stainless steel and flexible body jewellery polymers is not a materials footnote, it is the physical variable that determines whether a fistula heals cleanly or fights its jewellery. This article unpacks the Young's modulus numbers, the fourth-power relationship between bar diameter and bending stiffness, the cyclic loading patterns that drive irritation bumps, and the contact-pressure mechanics that separate rigid metal from compliant polymer performance in high-movement piercings.
