Phase-field modeling and simulation of fracture in brittle materials with strongly anisotropic surface energy

Crack propagation in brittle materials with anisotropic surface energy is important in applications involving
single crystals, extruded polymers, or geological and organic materials. Furthermore, when this anisotropy
is strong, the phenomenology of crack propagation becomes very rich, with forbidden crack propagation
directions or complex sawtooth crack patterns. This problem interrogates fundamental issues in fracture
mechanics, including the principles behind the selection of crack direction. Here, we propose a variational

Stress Recovery in XFEM

Hello all,

I am new to imechanica so pls forgive me if I make a mistake.

I have a coplue of doubts while recovering stresses from XFEM.

My problem statement has an inclusion with some eigen strain, embedded in  an infinite matrix. I have solved the problem for displacements using XFEM. I need to get the stresses at a point close to the interface.

New introductory course in structural mechanics opens on edX

2.01x: Elements of Structures is a new introductory course in structural mechanics that just started on edX. Anybody can  register  to audit the course for free. 

Course material includes lecture videos, tutorials, example problems, recitation problems with video walkthrough, homework problems, "boardnotes" (condensed lecture notes) and synoptic tables.

Solution of Post-Buckling& Limit Load Problems, Without Inverting the Tangent Stiffness Matrix& Without Using Arc-Length Methods

Solution of Post-Buckling & Limit Load Problems, Without Inverting the Tangent Stiffness Matrix & Without Using Arc-Length Methods

Homogenization - If materials in the model are isotropic, is it possible to get truly anisotropic resulting material?


I read that "In general, even if the materials on the micro-level are isotropic, the effective 

material can show anisotropic behavior. A general anisotropic linear elastic material 

may have twenty one independent material parameters.''


If I understand my results correctly then simple structures like ''ball in the unit cell'' result in orthotropic material.

I am a bit puzzled - what would be the simplest structure that would result in anisotropic material behaviour?

 Dear all,

 Sometimes, we can see the conception of Mandel Stress, I wonder

What is mandel stress? How to use it?


The 2nd Sandia Fracture Challenge is here!

update, 7/24/2014: The information packet ("SFC2-challenge-v5.ppt") is no longer attached to this post (iMechanica has a file size limit of 1 MB, so we can not attach the 6 MB file). IF YOU WOULD LIKE THE INFO PACKET, PLEASE E-MAIL ME, and copy Dr. Sharlotte Kramer, If you have an older version of the information packet, please also e-mail for the newest (v5) info packet.

We intend to send the shear calibration data to all those whose e-mail address I have by August 1st (sorry for the delay!).
