Dear all,
Just in case it is of interest to some of you, we provide links to three postprints related to our Abaqus implementation of the X-FEM. The latest is an "article in press" in Eng Frac Mech where we explain the essentials of the implementation and provide a link to the source code for the Abaqus computation. Note that the implementation is limited to 2D and the pre-processing code needed for element subdivision is not provided.
The Division of Engineering and Applied Science at the
California Institute of Technology invites applications for a tenure-track
faculty position at the level of assistant professor in solid, structural or
computational mechanics, with a preference in space applications. For details

Dear All,
A new multi-million pound initiative to fund research collaborations and improve links between UK and overseas researchers has been launched.
The Newton International Fellowships aim to attract the most promising, early stage, post-doctoral researchers working overseas, who do not hold UK citizenship, in the fields of humanities, engineering, natural
and social sciences.
Hello,
I have been reading up a lot on "Configurational Mechanics" and frankly i came up with a lot of questions. I am not skeptical at all about it, it just that many things are not clear to me.
When a bi-material sample for the characterization of interfacial fracture toughness is manufactured, the sample is not usually stress-free at room temperature. If an interface between a metallic substrate and a polymeric adhesive is considered, there are essentially two sources of residual stresses for a dry sample at room temperature:
1- The mismatch between the Coefficient of Thermal Expansion (CTE) of adhesive and substrate induces a concave or convex warpage, depending on the CTE values of the two materials.
The key to developing materials against failure under extreme environments is the understanding of the interplay between the various physical scales present, from the atomic level interactions, to the microstructural composition and the macroscale behavior. The ability to do this requires new methods that can be used to predict macroscale properties accurately based on microstructures and nanostructures without resorting to empiricism.
Hi, how the Peach-Koelher force acts on a dislocation?, I understand when the resolved shear stress acts on a dislocation. But not quite the term that provokes climb on an edge dislocation...
does anyone know any current theories on the stress wave propagation in a complex media(such as concrete or rock).(1D sphere wave or complex)
all i see is the simulation with a complex constitutive model. but i think it`s not perfect.
hope for your help
