Analysis of high velocity impacts of quasibrittle material fragments with a Hopkinson bar [PDF]

open access: yesEPJ Web of Conferences, 2021
In this work it has been characterized the impact behaviour of quasibrittle fragments against a Hopkinson bar in a wide range of impact velocities (70-180 m/s). Hopkinson bar is designed to measure the impact forces thanks to a proper instrumentation. In

Feed-Forward Neural Networks for Failure Mechanics Problems

open access: yesApplied Sciences, 2021
This work addresses an efficient neural network (NN) representation for the phase-field modeling of isotropic brittle fracture. In recent years, data-driven approaches, such as neural networks, have become an active research field in mechanics.

Continuum Nanofluidics [PDF]

open access: yesLangmuir, 2015
This paper introduces the fundamental continuum theory governing momentum transport in isotropic nanofluidic flows. The theory is an extension to the classical Navier-Stokes equation, which includes coupling between translational and rotational degrees of freedom, as well as non-local response functions that incorporates spatial correlations.

Longitudinal Variations in Physiochemical Conditions and Their Consequent Effect on Phytoplankton Functional Diversity Within a Subtropical System of Cascade Reservoirs

open access: yesFrontiers in Ecology and Evolution, 2022
The social and environmental impacts of large dams are quantifiable and have been well documented, while small dams have often been presumed to be less environmentally damaging than large dams.

Modeling of Cell Nuclear Mechanics: Classes, Components, and Applications

open access: yesCells, 2020
Cell nuclei are paramount for both cellular function and mechanical stability. These two roles of nuclei are intertwined as altered mechanical properties of nuclei are associated with altered cell behavior and disease.
