Toughness due to hysteretic deformation

These fragments of notes are intended for a course on fracture mechanics, but I have always run out of time, and have never managed to go over them in class.  Some of the ideas are mentioned in various parts of the class.  I have also listed refeences and review articles.

The stress intensity factor and Young's Modulus

The stress intensity factor and Young's Modulus 

It is evident that stress intensity factor considered as  the most important factor in fracture mechanics which used for evaluating the stress state near to tip crack . However this factor depends up many parameters (such us normal loading, cracks size and its geometry). my question is as follow 

cell mechanics

Experimental studies recently performed on single cancer and healthy cells have demonstrated that the former are about 70% softer than the latter, regardless of the cell lines and the measurement technique used for determining the mechanical properties.

[Call for Abstracts] SES minisymposium on Friction, Fracture, and Damage

Dear Colleagues,

We would like to invite you to consider submitting abstracts to the following minisymposium taking place as part of the Soceity of Engineering Sciences meeting to be hosted by the University of Maryland (October 4-7, 2016)

D-9 :Friction, Fracture and damage (http://ses2016.org/symposium-d-9-friction-fracture-and-damage/)

Simpleware at North Star Imaging 30th Anniversary Symposium, May 11-12 2016

May 11 - 12, 2016 - St. Michael Cinema, St. Michael, MN

This two-day conference will include national and international speakers discussing the latest in Digital Radiography and Computed Tomography systems and technology. Current users of X-ray and Computed Tomography will gain more knowledge to improve their operations. Those new to the X-ray/CT scanning will hear from peers how they utilize the technology within their industry.

Generate master curve for viscoelasticity

Choose a channel featured in the header of iMechanica: 

Hello,

I would like to generate a master curve (e.g. of the storage modulus) based on frequency-sweeps experiment for different temperatures.

Basically, I need to determine the shifts in order to construct the master curve. I want to automatize the process with Matlab, instead of shifting the data by hand. And I don't want to use WLF or Arrhenius methods.

I want to determine the shifts for each temperature s.t. I get a smooth master curve (minimize the error using least square).

Fully funded PhD opportunity for International Students

I have a fully funded PhD position (3 years duration) for students from any nationality to work on an excited simulation based project to elucidate details of diamond machining of silicon at Queen's University of Belfast. A world leading Paris based industry delivering silicon PV cells have extended their financial assistance to work on this rewarding project. Candidates having good background in mechanics/ manufacturing are very much encouraged to write to me at s.goel@qub.ac.uk

Yield behaviour of trabecular bone

A recently published paper  "Evaluating the macroscopic yield behaviour of trabecular bone using a nonlinear homogenisation approach" links the micromechanics of bone to its macroscopic behaviour. The paper may be of interest to colleagues on this forum. The abstract is provided below.
