Segmenting mechanically heterogeneous domains via unsupervised learning
Biomech Model Mechanobiol. 2024 Jan 13. doi: 10.1007/s10237-023-01779-2. Online ahead of print.ABSTRACTFrom biological organs to soft robotics, highly deformable materials are essential components of natural and engineered systems. These highly deformable materials can have heterogeneous material properties, and can experience heterogeneous deformations with or without underlying material heterogeneity. Many recent works have established that computational modeling approaches are well suited for understanding and predicting the consequences of material heterogeneity and for interpreting observed heterogeneous strain fields...

Multiscale mechanical characterisation of the craniofacial system under external forces
Biomech Model Mechanobiol. 2024 Jan 13. doi: 10.1007/s10237-023-01799-y. Online ahead of print.ABSTRACTPremature fusion of craniofacial joints, i.e. sutures, is a major clinical condition. This condition affects children and often requires numerous invasive surgeries to correct. Minimally invasive external loading of the skull has shown some success in achieving therapeutic effects in a mouse model of this condition, promising a new non-invasive treatment approach. However, our fundamental understanding of the level of deformation that such loading has induced across the sutures, leading to the effects observed is severely...

Investigation of direction- and age-dependent prestretch in mouse cranial dura mater
Biomech Model Mechanobiol. 2024 Jan 11. doi: 10.1007/s10237-023-01802-6. Online ahead of print.ABSTRACTCranial dura mater is a dense interwoven vascularized connective tissue that helps regulate neurocranial remodeling by responding to strains from the growing brain. Previous ex vivo experimentation has failed to account for the role of prestretch in the mechanical behavior of the dura. Here we aim to estimate the prestretch in mouse cranial dura mater and determine its dependency on direction and age. We performed transverse and longitudinal incisions in parietal dura excised from newborn (day [Formula: see text]4) and ma...
