Anisotropic Shear Properties of Organic Interfaces in Bio‐composite Materials
Advanced Functional Materials, EarlyView.A novel cantilever design enables direct probing of shear properties at single organic interfaces within biocomposite prismatic ultrastructures. By decoupling lateral and torsional shear responses, the method reveals isotropic behavior in Atrina vexillum and pronounced anisotropy in Unio pictorum.

Static and Dynamic Responses of Micro-Structured Beams
Applied Sciences, 2020 In this study, we developed a one-dimensional Timoshenko beam model, embedded in a 3D space for static and dynamic analyses of beam-like structures. These are grid cylinders, that is, micro-structured bodies, made of a periodic and specifically designed ...
