Latest progresses on the phase field model for brittle fracture

marco.paggi's picture

Dear Fracture mechanician,

In my group we published 2 articles with novelties on the phase field model for brittle fracture:

 

1. New formulation that combines the phase field model of brittle fracture and the interface cohesive zone model, recovering the fundamental solutions by He and Hutchinson on crack deflection vs. penetration at an interface, and further generalizing them to cohesive fracture: http://www.sciencedirect.com/science/article/pii/S0045782516317066

 

2. Implementation of the phase field model of fracture in solid shells for geometrical and mechanical nonlinear problems, with ANS and EAS techniques to avoid locking, and with interpolation of the phase field through the thickness:

If you are interested in collaborations on these topics, please contact marco.paggi@imtlucca.it 

 

As ever,

<p>One of the most fascinating progresses that have been made in computational fracture mechanics in recent years! Theoretically elegant and useful in many fields! Nice work!&nbsp;<span style="color: #333333; font-family: arial; font-size: 24px; line-height: 24px; background-color: #ffffff;"><br /></span></p>

has been extended to study dynamic fracture, brittle fracture, ductile fracture, fracture in anisotropic materials, plastic materials, porous materials ,hyperelastic materials and viscoplastic materials. ....

It can be coupled with other physical processes such as diffusion, phase transformation and deformation twinning, etc. Its rapid development in recent years is really amazing. The method itself is theoretically elegant and easy

to be implemented.  Worthy to work on! I like it very much. :-)

We just submitted today a proposal for a minisymposium at the next WCCM 2018 conference in New York on

Open challenges in the phase field approach to fracture mechanics

This minisymposium aims at gathering together experts in computational fracture mechanics to discuss open challenges and generalizations of the phase field approach to fracture (PFAF). Selected original contributions will be invited for being considered for publication into a special issue of an international journal.

Topics of interest are (but are not limited to):
- Generalization of the PFAF to viscoelastic materials;
- Generalization of the PFAF to mechanical and geometrical nonlinear problems;
- Generalization of the PFAF to dynamics;
- Generalization of the PFAF to anisotropic and/or inhomogeneous materials;
- Generalization of the PFAF to interface fracture problems;
- Implementation of the PFAF in finite element technologies;
- Interaction between PFAF and cohesive zone models;
- Comparison between the PFAF and other fracture mechanics/damage mechanics formulations;
- Prediction of size-scale effects;
- Modelling of fatigue crack growth.

 

If accepted, we will post an update with a link for abstract submission.

It could be a nice opportunity to discuss on common research.
