The quantum character of buckling instabilities in thin rods
T. A. Engstrom
Here the buckling of inextensible rods due to axial body forces is mapped to 1d, nonrelativistic, time-independent quantum mechanics. Focusing on the pedagogical case of rods confi…
Loops versus lines and the compression stiffening of cells
M. C. Gandikota, Katarzyna Pogoda, Anne van Oosten +4
Both animal and plant tissue exhibit a nonlinear rheological phenomenon known as compression stiffening, or an increase in moduli with increasing uniaxial compressive strain. Does…
Buckling without bending: a new paradigm in morphogenesis
T. A. Engstrom, Teng Zhang, A. K. Lawton +2
A curious feature of organ and organoid morphogenesis is that in certain cases, spatial oscillations in the thickness of the growing "film" are out-of-phase with the deformation of…
Compression stiffening in biological tissues: on the possibility of classic elasticity origins
T. A. Engstrom, K. Pogoda, K. Cruz +2
Compression stiffening, or an increase in shear modulus with increasing compressive strain, has been observed in recent rheometry experiments on brain, liver, and fat tissues. Here…
