On axisymmetric/diamond-like mode transitions in axially compressed core-shell cylinders
Recent interests in curvature- and stress-induced pattern formation and pattern selection motivate the present study. Surface morphological wrinkling of a cylindrical shell supported by a soft core subjected to axial compression is investigated based on a nonlinear 3D finite element model. The post-buckling behavior of core-shell cylinders beyond the first bifurcation often leads to complicated responses with surface mode transitions. The proposed finite element framework allows predicting and tracing these bifurcation portraits from a quantitative standpoint.

Abaqus - line load on channel beam applied outside of a beam (in shear center)
Hello, everybody. I'm having a problem regarding the application of a line load beyond the contours of a channel tube made out of shell elements. I am trying to perform lateral torsional buckling analysis and the load needs to act in shear center. Does anybody have a solution for this?
Yield behaviour of trabecular bone
A recently published paper "Evaluating the macroscopic yield behaviour of trabecular bone using a nonlinear homogenisation approach" links the micromechanics of bone to its macroscopic behaviour. The paper may be of interest to colleagues on this forum. The abstract is provided below.

Fracto-emission in lanthanum-based metallic glass microwires under quasi-static tensile loading
Plastic deformation in metallic glasses is highly localized and often associated with shear banding, which may cause momentary release of heat upon fracture. Here, we report an explosive fracture phenomenon associated with momentary (∼10 ms) light emission (flash) in Lanthanum-based (LaAlNi) metallic glass microwires (dia. ∼50 μm) under quasi-static tensile loading.
