Distributed dislocation approach for cracks in couple-stress elasticity: Shear modes [PDF]
The distributed dislocation technique proved to be in the past an effective approach in studying crack problems within classical elasticity. The present work aims at extending this technique in studying crack problems within couple-stress elasticity, i.e.

The coupling of translational control and stress responses [PDF]
Abstract The translation of messenger RNA (mRNA) into protein is a multistep process by which genetic information transcribed into an mRNA is decoded to produce a specific polypeptide chain of amino acids. Ribosomes play a central role in translation by coordinately working with various translation regulatory factors and aminoacyl ...

Uniqueness for plane crack problems in dipolar gradient elasticity and in couple-stress elasticity [PDF]
The present work deals with the uniqueness theorem for plane crack problems in solids characterized by dipolar gradient elasticity. The theory of gradient elasticity derives from considerations of microstructure in elastic continua [Mindlin, R.D., 1964 ...
