Surface microstructures developed on polished quartz crystals embedded in wet quartz sand compacted under hydrothermal conditions

open access: yesScientific Reports, 2021
Intergranular pressure solution plays a key role as a deformation mechanism during diagenesis and in fault sealing and healing. Here, we present microstructural observations following experiments conducted on quartz aggregates under conditions known to ...

Finite element modeling of the behavior of polymethyl-methacrylate (PMMA) during high pressure torsion process

open access: yesFracture and Structural Integrity, 2020
High Pressure Torsion (HPT) is a highly effective super-plastic deformation process for obtaining nano-materials with high performance mechanical properties. In view of its optimization, it is of paramount importance to evaluate the relations between the

HPT and cocyclic operations [PDF]

open access: yesHomology, Homotopy and Applications, 2005
We reinterpret the classical theory of cocyclic operations in terms of permutations and homotopy equivalences of explicit chains. The essential tools we use are Homological Perturbation Theory and Eilenberg–Zilber Theorem. The main objective of this technique is the final identification of cohomology operations at cochain level.
