fracture

I attach Barenblatt's paper which is difficult to access. The paper includes a milestone idea of the cohesive surface that  allows us to get rid of unphysical singularities in the older formulations of fracture mechanics.

I am teaching Subsea Integrity for the MSc students majoring in Subsea Engineering at the School of Engineering, University of Aberdeen. This is a course that combines the fundamental principles (corrosion, fracture, fatigue and material selection) with the industry applications (subsea integrity management and implementation, cathodic protection, case studies on subsea reliability and engineering assurance).

Teaching time schedule

A fully funded PhD position is available in the area of multi-scale modeling of geomaterials within the research project Failure of cohesive geomaterials: bridging the scales - GEOBRIDGE at Laboratoire Sols, Solides, Structures – Risques (3S-R), Université Joseph Fourier, Grenoble, France. 

there are two analytical concepts that are very important in fatigue failure.the first one is crack closure and the others is residual stress .the first one is in behind of crack and the other emphasis in the front of crack tip. the question is if we use some devices such as AFM/SEM is it possible we model the energy filed during fatigue process?   if this idea can be investigated the second question can be asked: is there any similarity to model for different loading conditions? 

I appreciate if you also put your comment in my idea?

Hi all,

       Can Hydrostatic stress be used as a fracture criteria? If so can critical hydrostatic stress be found experimentally? Thanks.
