On the Afferrante-Carbone theory of ultratough peeling

Submitted by Mike Ciavarella on Mon, 12/07/2020 - 08:11

I attach a preprint of a note on the elegant and interesting and simple theory by Afferrante and Carbone on ultratough peeling of an elastic tape from a viscoelastic substrate. Any comment is most welcome. Regards, MC

Abstract

In the 100 000 top scientists there is decline of USA, and a jump of China and India

Submitted by Mike Ciavarella on Sat, 10/19/2019 - 19:01

Not everyone has noticed, also from our previous studies including a letter to Nature, that in the list of 100 000 most cited scientists by Ioannides et al. recently published in PLOS Biology, comparing the career database (1996-2017) with that of 2017, composed of around 2% of Italians, all the states we analysed except for Italy and China and India have suffered a decline in the number of researchers present in the 2017 data set compared to even substantial career data (Japan –20% nationally ).

Analytical Models for Fatigue Life Prediction of Metals in the Stress-Life Approach -- phd thesis by Pietro D’Antuono

Submitted by Mike Ciavarella on Sat, 10/19/2019 - 18:49

dear collegues

I'd be very grateful if you could have a look, if not a deep reading, at the phd thesis of my last student, playing on classical results on uniaxial fatigue, but with a view of simple, unified perspective on constant and varying amplitude fatigue. We made large use of e-fatigue.com web site and the data in there.

Thanks in advance for any remark. The final thesis will be submitted in few weeks time.
