Mathematical Modelling and Analysis of Complex Fluids and Active Media in Evolving Domains

Passive mechanical response of skeletal muscles at fast time scales is dominated by long range interactions inducing cooperative behavior without breaking the detailed balance. This leads to such unusual ‘material properties’ as negative equilibrium stiffness and different behavior in force and displacement controlled loading conditions. Careful fitting of experimental data suggests that ‘muscle material’ is finely tuned to perform close to a critical point.
