fracture

The fatigue behavior of Ag films on polyethyleneterephthalate substrates was studied using electrical resistance measurements.
Scanning electron microscopy images showed two types of failure: typical fatigue failure with extrusion–intrusion pairs, and ductile
failure with local necking. Once through-thickness cracks are formed in the metal layer, cracks propagate and the resistance increases abruptly for both failure modes. The effect of adhesion on fatigue life is discussed in terms of concurrent delamination, crack initiation and propagation.

Dear colleagues,



We are organizing a symposium titled "Fundamentals of Fracture" at the 2013 Spring Meeting of the German Physical Society, taking place in Regensburg, Germany.



The aim of this international symposium is to bring together specialists from the fields of solid state physics, materials science, continuum mechanics, statistical physics and mathematics to discuss  the latest scientific developments related to fundamental mechanisms and physics of fracture.

Dear all,

Please find enclosed our paper which is published on Journal of Multiscale Modelling
Vol. 3, No. 4 (2011) 1–42 which gives an overview of state of the art multiscale techniques for material modeling. 

The paper discusses the following topics: homogenization, Representative volume element, computational homogenization (Fe2 methods) for both both bulk materials and strong discontinuities. 

I hope the paper is useful for beginners to the field.

All the bests, 

Hello everyone,

One of the papers from the 'past' (but still quite actual...I think) and maybe of some interest to various communities. 

Abstract:

A system in which one adherend had two types of surface treatment was tested using a wedge test.

Simple polishing and polishing with subsequent sandblasting were the

treatments used, with a distinct straight line, perpendicular to the sample edges,

separating the two. Despite the clear-cut difference in surface treatment, smooth

ME/PhD Positions open:   Fracture Simulation for Visual Effects

High speed simulations of the fracture of wood, glass, concrete, brick walls, and many other materials are used every day in the visual
effects industry. The project team will develop the next generation of fracture effects technology, bringing visual effects fracturing to the next level through novel computational methods in conjunction with realistic material models for deformation and fracture.
