In 2007 I wrote a question in Imechanica, IS THERE NO PULL-OFF FOR ADHESIVE FRACTAL SURFACES?
Clearly, in 2007 this question was too hard to answer. I pointed there that Fuller and Tabor 1975 asperity theory predicted a weird limit for a true fractal surface, that of no stickiness for any fractal dimension or amplitude, in the limit.

THE SECOND INTERNATIONAL CONFERENCE ON “SUSTAINABLE
MATERIALS PROCESSING AND MANUFACTURING”
North West, Sun City Resort, South Africa | March 8 - 10, 2019
Lattice models are popular methods for simulating deformation of solids by discretizing continuum structures into spring networks. Despite the simplicity and efficiency, most lattice models only rigorously converge to continuum models for lattices with regular shapes. Here, we derive a lattice model for neo-Hookean solids directly from finite element methods (FEM). The proposed lattice model can handle complicated geometries and tune the material compressibility without significantly increasing the complexity of the model.
Dear Colleagues,
The SEM 2019 annual conference abstract deadline has been extended to October 24, 2018. Please see the Call for Abstracts below and consider submitting an abstract.
We invite you to submit a paper to the 2019 Society for Experimental Mechanics (SEM) Annual Meeting in one of the many sessions in the Fatigue and Fracture Track. See below for further information on these sessions, and please forward this to others who may be interested.
Applications are invited for a postdoctoral position in the Joost Vlassak group at Harvard University with an expected start date of October 1, 2018. This goal of this position is to develop new calorimetric sensing technologies and use these to study cellular bioenergetics and thermodynamics of materials. This highly interdisciplinary project includes the development of new devices and sensing systems, materials characterization, and cellular biology.
Two PhD positions are available at the University of Southampton in the areas of:
(1) Computational modelling of complex structures and structured materials - especially those fabricated using additive manufacturing,

and
(2) Elastic and acoustic metamaterials using additive manufacturing.
Tissue Mechanics Lab at Georgia Tech has an immediate opening position for a Postdoc fellow. The candidate should have research experience in cardiovascular solid mechanics. Previous experience in machine learning is a plus. For more information, please contact Dr. Sun at:
Wei Sun, Ph.D, FAHA
Associate Professor of the Wallace H. Coulter Department of Biomedical Engineering
Georgia Institute of Technology and Emory University
Technology Enterprise Park, Room 206
387 Technology Circle, Atlanta, GA 30313-2412
The two slides intend to show the quantum mechancal origin of the surface energy. The slides suplement a course on Fracture Mechanics.
Postdoctoral Position in in Computational Mechanics of Structured Coatings is available at Technical University of Denmark, DTU Wind Energy.
We have an open PhD position starting in the Fall semester 2019 at the Computational Laboratory for the Mechanics of Interfaces at the University of Tennessee - Knoxville (http://clmi.utk.edu). The research topic centers upon the modeling of texture evolution during processing conditions of titanium alloys using dislocation density based crystal plasticity. Efficient computational algorithms will be pursued to couple the specimen/part scale and the mesoscale.
