Dear all,
I am trying to find the crack tip SIF in Polyurethane which an elastomer. It behaves like a nonlinear elastic material with the initial small linear elastic region. Can I use a multi-parameter stress field equation (William's crack tip stress field equation) to get the SIF of the crack tip.
Thank you

https://doi.org/10.1016/j.msec.2018.01.007 The present review will introduce the basic concepts of silk-based electronics/optoelectronics including the latest technological advances on the use of silk fibroin in combination with other functional components, with an emphasis on improving the performance of next-generation silk-based materials. It also highlights the patterning of silk fibroin to produce micro/nano-scale features, as well as the functionalization of silk fibroin to impart antimicrobial (i.e. antibacterial) properties.

Dear all
In the experiment setup, the fatigue loading spectrum has a loop of 2 blocks of load amplitude. First load amplitude the higher applied for 2X time period followed by lower load amplitude for X time period then the loop repeated till failure. the load sequence was High-Low and Low-High in this loop. X was in thousands so might be suggested as the cyclic response will be stabilized in the first 10 cycles, the first block will dominate the fatigue behaviour at least till fracture, or damage initiation.
