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.

Hello,

I would like to generate a master curve (e.g. of the storage modulus) based on frequency-sweeps experiment for different temperatures.

Basically, I need to determine the shifts in order to construct the master curve. I want to automatize the process with Matlab, instead of shifting the data by hand. And I don't want to use WLF or Arrhenius methods.

I want to determine the shifts for each temperature s.t. I get a smooth master curve (minimize the error using least square).
