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

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

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.

Please help with articlea

Hello,

Seeking Help: Can anyone share a copy of the following articles: P.C. Bregman, M. Kuipers, H.L.J. Teerling, W.A. van der Veen. Strength and stiffness of a flexible high-pressure spiral hose. Acta Mechanica 97, 185-204 (1993) and B.A. van den Horn & M. Kuipers. Strength and stiffness of a reinforced flexible hose. Applied Scientific Research 45: 251-281 (1988) (which I had and somehow lost).

Thanks in advance

Simultaneous improvements of strength and toughness in topologically interlocked ceramics, Mirkhalaf, Zhou, Barthelat, PNAS, 2018

Novelty/impact/significance:

Develop a topologically interlocked material (TIM) design that is tougher (25-50X) and stronger (1.2X) than the monolithic plates with the same material (increasing impact resistance without sacrificing strength/toughness).

PhD position in experimental materials and mechanics - University of Alabama

We seek a full-time Ph.D. student to work on the transmission electron microscopy (TEM) of nickel-based superalloys in the Department of Mechanical Engineering at the University of Alabama. The position will start in January 2021 and will be for four years. It will be funded through a new NSF project on surface engineering of the nickel-based superalloys. The goal is to explore and understand the strengthening and precipitate interactions.

Stress intensity factor from Abaqus

 How we can calculate K1 value from J - integral result from abaqus?. K1 value directly from abaqus is reliable? Because its crack initiation criterion is Max tangential stress, Max energy release rate and KII= 0. Which criterion will give correct results? Its depends on problem we handle. Thats I know. But if no value is available for crack initiation criterion ( Also, I introduce crack initially.
