dear collegues
I have been attracted recently by a theory from Shrimali and Lopez-Pamies which is based on experimental evidence obtained from Suo's group in Harvard in 2012 in a (limited, but significant) set of experiments on rubber. The theory assumes that the stretch to nucleating a crack is constant and independent on stretch rate. The theory is then built on that, to predict the increase of fracture energy with rate.

dear Colleagues
In writing a review of models on fretting fatigue, I am looking at the effect of friction coefficient. Obviously, if friction is zero there is no fretting fatigue! This goes without saying.
In rail-wheel contact modelling, there is a huge industrial interest to model accurately rolling contact of hard bodies with friction for predicting fatigue, squeal, noise, vehicle dynamics. In the literature, the case of Carter 1926 has been extended with numerical codes known as FASTSIM and CONTACT which are based on algorithms by JJ Kalker. However, there is a serious problem to model falling rate-dependent friction, which gives unexpected instabilities and unclear solutions.
dear collegues, I may be interested to share your views on an "asperity theory" modified Persson's rubber friction contact mechanics theory which I find not clearly motivated and seems to lead to erroneous conclusions ---- but I am also unable to reproduce the results claimed by the authors. The preprint is here, and the original paper attached: https://www.researchgate.net/publication/359392510
