Mechanics of growth and rupture of abdominal aortic aneurysm
We present a coupled mathematical model of growth and failure of the abdominal aortic aneurysm (AAA). The failure portion of the model is based on the constitutive theory of softening hyperelasticity where the classical hyperelastic law is enhanced with a new constant indicating the maximum energy that an infinitesimal material volume can accumulate without failure. The new constant controls material failure and it can be interpreted as the average energy of molecular bonds from the microstructural standpoint.
Mechanics of microtubule buckling in living cells
As the most rigid cytoskeletal filaments, microtubules bear compressive forces in living cells, balancing the tensile forces within the cytoskeleton to maintain the cell shape. It is often observed that, in living cells, microtubules under compression severely buckle into short wavelengths. By contrast, when compressed, isolated microtubules in vitro buckle into single long-wavelength arcs. The critical buckling force of the microtubules in vitro is two orders of magnitude lower than that of the microtubules in living cells.

You'll find tons of video about biological experiments you might be interested in. It is very useful for most of mechanicians who lack this kind of knowledge and experience. Enjoy yourself!
ON THE MECHANICS OF HELIX
Helix is a very interesting structure. There are many biopolymers that have a helical structure.
- How can someone model the helix in mechanics?
- How can the helix reinforce a rod?
- How does this structure reflect the mechanical properties of biopolymers?
