Viscoelasticity of multicellular system represents a product of energy storage and dissipation
during cell rearrangement under various stress or strain conditions and should be
considered in the context of cellular ability to relax obtained at various time scales. Various
scenarios of relaxation are described by various constitutive models and can be considered
in the time domain and frequency domain. Time domain corresponds to stress and strain
change versus time while the frequency domain corresponds to interrelation between …
