Dear Colleagues,

We would like to cordially invite you to submit an abstract to our symposium titled “electro-chemo-mechanics of energy materials” as part of the 18th U.S. National Congress for Theoretical and Applied Mechanics Conference. The conference will be hosted by Northwestern University, Chicago in June 5-9, 2018.

Hello All,

There is a potential opening for a PhD student in Prof. Nadimpalli’s group at the New Jersey Institute of Technology starting from Fall2017. Candidates with good academic credentials and an interest to work in experimental research projects are encouraged to apply. Ideal candidate should have a master’s degree in mechanical/materials science/aerospace or related field with a good background in Solid Mechanics, Materials Science, and Experimental Methods (including but not limited to SEM, TEM, and nanofabrication methods).

Hi All,

I have a question in my mind, we all know that the fracture toughness of isotropic, homogeneous materials is dependent on state of stress (plane strain and plane stress). It is higher in case of plane stress and decreases as the constraint increases and attains a constant value which we call "plane strain fracture toughness". But, what about the fracture toughness in interfaces? or fracture of thin layer bonded between two substrates (adhesive type)? I am sure that it will be a function of this as well.
