5.1 Elastic stress transfer, in Chapter 5. Composite mechanics: Short fibers, in Load Bearing Fiber Composites, by Michael R. Piggott, 2002
This time reading notes on a section of a well-known mechanics book are presented, due to its extreme clarity and reader-friendliness in explaining the stress transfer in fiber-reinforced composites. Personal understanding for the micromechanical model and derivations are included accordingly without specific indications.

Materials become insensitive to flaws at nanoscale: Lessons from nature, Gao, Ji, Jger, Arzt, Fratzl, PNAS, 2003
Novelty/impact/significance:
It is firstly/ingeniously demonstrated that the biological nanocomposites’ generic structure is mechanically advantageous: the nanometer size of mineral reinforcements is selected to ensure optimum strength and maximum tolerance of flaws. The derivations are simple and effective.

On the Afferrante-Carbone theory of ultratough peeling
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
