Kinetic relations and local energy balance for LEFM from a nonlocal peridynamic model

Journal: International Journal of Fracture

Abstract: A simple nonlocal field theory of peridynamic type is applied to model brittle fracture. The kinetic relation for the crack tip velocity given by Linear Elastic Fracture Mechanics (LEFM) is recovered directly from the nonlocal dynamics, this is seen both theoretically and in simulations. An explicit formula for the change of internal energy inside a neighborhood enclosing the crack tip is found for the nonlocal model and applied to LEFM.

Roughness-Induced Adhesion

Adhesion and fracture; adhesion; contact mechanics; friction;

Usually, roughness destroys adhesion and this is one of the reasons why the "adhesion paradox", i.e. a "sticky Universe", is not real. However, at least with some special type of roughness, there is even the case of adhesion enhancement, as it was shown clearly by Guduru, who considered the contact between a sphere and a wavy axisymmetric single scale roughness, in the limit of short-range adhesion (JKR limit).

Determining fermi energy

Ask iMechanica

Hi everyone.

 

I want to determine Fermi energy from the band structure of a conductor and a semiconductor.

I believe that for semiconductors, it is given by the average of highest energy in the valence band and the lowest energy in the conduction band. Please correct me if required.

I am wondering how to obtain fermi energy for conductors where those two bands are overlapping.

 

Thanks in advance.
