In the review paper by Spak & al. (January 2013) on cable bending mechanical models, one class of models was not specifically mentioned, in which authors attempt to take into account the tangential elasticity at points of contact between cable layers. There are at least two noteworthy contributions:

Hello everyone
I have a question about Abaqus verification for a Mooney-Rivlin
hyperelastic material example which exist in ABAQUS Documentation/Abaqus
Verification Manual/2.2.1 Elastic materials/VIII. Hyperelasticity with
Mooney-Rivlin strain energy function. In the example for a Test data
input-uni axial tension the company Defined a stress-strain curve as
input for material property(Nominal stress-Nominal strain). But when I
plot these parameters(Stress -nominal strain) as output of the software
Hi mechanicians:
I decided to post because I have an inconvenience that is not shown in other posts.
I am working in the Abaqus - Fortran environment in a thermal analysis. After implementing a new procedure (which actually works), the .sta file shows me that it has problems in its unique step, more or less in the 60th iteration (it is supposed to get until 500). Twenty iterations after that gets into interruptions because the code cannot converge.
With these lines it is easier to understand my point:
You are welcome to submit an abstract to the MS 101 "Modeling of surface effects in nanomaterials and heterostructures" at the APCOM & ISCM 2013 conference (Singapore, 11-14th December, 2013), organized by prof. H.L. Duan (Peking University, Beijing) and myself.

The deadline for abstract submission has been extended to 15th May 2013.
Loooking forward to see you in Singapore.
The Biosystems and Biomaterials Group at NIST has two postdoctoral positions available for recent PhD graduate to work on (1) simulation of photon transport (light migration) in polymeric composites (2) modeling of cell-material adhesive interactions. These interdisciplinary research programs require the prospective applicants to have a strong background in computational methods (finite element or MD). For the cell-material interaction, candidates with prior experience on biophysics are preferred.
The Department of Mechanical Engineering at Politecnico di Milano is
currently seeking applicants for PhD positions in the following research areas:

What do
Guitar Strings Have to do With Dynamic Response?
Tightening
guitar strings to change the sound uses the same principle as tightening head
bolts to change the dynamic response of an engine block assembly. This is
stress stiffening and it affects the dynamic response of a structure. One of
the fundamental components in assessing nonlinear static stress is stress
stiffening, but it is also the most overlooked when evaluating the steady-state
dynamic response of engine assemblies.
