A T-stress is generally not expected to contribute to the stress intensity factor because its contribution to the free energy is the same before and after crack growth. Nothing lost, nothing gained. Some time ago I came across a situation when a T-stress, violates this statement. The scene is the atomic level. As the crack is producing new crack surfaces the elastic stiffness in the few atomic layers closest to the crack plane are modified. This changes the elastic energy which could provide, contribute to or at least modify the energy release rate.

Dear colleagues,

We would like to invite you to submit an abstract to the symposium (351) on "Nonlinear Mechanics of Polymer Network: Elasticity, Inelasticity, and Temporal Evolution" at the 2018 U.S. National Congress for Theoretical and Applied Mechanics which will be held at Northwestern University (Chicago IL, USA) on June 4-9, 2018. You can find a description of the symposium and the conference website using this link.

Dear Colleagues, 

Dr. Dbakar Datta and I are co-organizing a session titled “Mechanics and Physics of 2D Crystalline Materials” (Track #1203) for the upcoming WCCM 2018 conference in New York City.

We would like to cordially invite you to submit an abstract to our session. The topics of this symposium include (but not limited to) the following:

18th US National Congress for Theoretical and Applied Mechanics (USNC/TAM) will be held in Chicago, Illinion, on Jun 4 to 9 2018. USNC/TAM is held every four years. http://sites.northwestern.edu/usnctam2018/

Dear Colleagues,

We would like to invite you to submit an abstract to our symposium titled “362 Failure and Damage in Soft Materials: From Instabilies to Cracking” as part of the 18^th U.S. National Congress for Theoretical and Applied Mechanics (Northwestern University in Chicago, IL, June 4-9, 2018).

The deadline for abstract submission is November 10, 2017.

Present your research at ICoBT2018, 26-29 September 2018, Montreal, Canada. Oral and poster abstracts are invited on the conference topics and should be submitted using the online submission system by 20 April 2018.

Skin is the largest organ of the human body, and it offers a diagnostic interface rich with vital biological signals from the inner organs, blood vessels, muscles, and dermis/epidermis. Soft, flexible, and stretchable electronic devices provide a novel platform to interface with soft tissues for robotic feedback and control, regenerative medicine, and continuous health monitoring.
