MS13 - Mechanics and Microstructural Behavior of Biological Media: from Multiscale Modeling to Simulations

Multiscale systems are widely present in both biological structures and technological applications. The ability to account not only for the macroscopic behavior of an elastic medium, but also for its microscopic arrangement, allows for a more complete and realistic description. Recently, I studied two problems in which a non-trivial interaction
arises between two contributions coming from...

MS13 - Mechanics and Microstructural Behavior of Biological Media: from Multiscale Modeling to Simulations

The iris is a deformable circular diaphragm that regulates pupil size in response
to changes in illumination through the antagonistic actions of sphincter and
dilator muscles. While the phenomenological relationship between pupil size
and light intensity is well studied, the mechanical interplay between active
muscle contraction and passive iris tissue remains poorly understood. In...

67. Modelling and simulation of anisotropic growth in brain tumours through poroelasticity: A study of ventricular compression and therapeutic protocols

MS13 - Mechanics and Microstructural Behavior of Biological Media: from Multiscale Modeling to Simulations

Brain tumors remain one of the most formidable challenges in medicine, largely due to their unpredictable localization and varying degrees of malignancy. Their notorious aggressiveness in spreading often limits the efficacy of standard treatments. As the tumor mass grows, it compresses and displaces surrounding healthy tissues, often altering the volume of the cerebral ventricles and...

88. A micromechanical finite element model of the retina

MS13 - Mechanics and Microstructural Behavior of Biological Media: from Multiscale Modeling to Simulations

In ocular biomechanics, the mechanical behaviour of the retina has received limited attention, as most studies have focused on the transduction of light into neuronal signals. Nevertheless, modelling retinal mechanics can provide valuable insights in the investigation of surgical procedures, such as subretinal injection, to evaluate the relevance of different surgical parameters on retinal...

117. Multiscale continuous spectrum description of human fibrous tissues under dynamic conditions

MS13 - Mechanics and Microstructural Behavior of Biological Media: from Multiscale Modeling to Simulations

Human fibrous tissues display a non-local in time mechanical behaviour since they have memory of their past stress-strain history and consequently they can be defined as hereditary materials. In particular, this unconventional behaviour can be mathematically described by introducing a fractional intermediate non-additive rheological model, the so-called springpot [1], to avoid the drawbacks...
