Extreme Mechanics Letters (EML) is thrilled to announce the appointment of Professor Xuanhe Zhao of the Massachusetts Institute of Technology (MIT) as Co-Editor-in-Chief of EML. Professor Zhao is a world-renowned expert in the mechanics of materials and soft robotics.
A compliantly fixed hemispherical indenter in adhesive contact with an elastic sample firmly bonded to a rigid base is considered under the assumption that the rigid base undergoes small-amplitude high-frequency normal (vertical) oscillations. A general law of the rate-dependent JKR-type adhesion is assumed, which relates the work of adhesion to the contact front velocity. Using the Bogoliubov averaging approach in combination with the method of harmonic balance, the leading-order asymptotic model is constructed for steady-state vibrations.
Fusion-based manufacturing techniques, such as laser welding and additive manufacturing, are revolutionising how we produce complex components across industries. Yet, one critical challenge persists: how do we reliably control and predict melt-pool behaviour to ensure high-quality outcomes? This question was at the heart of my PhD research, completed at Delft University of Technology in the Netherlands.
I am pleased to share our newest open-access article just published in #ActaMaterialia.
While stacked objects are ubiquitous, there are few works devoted to modeling their dynamics. In a new paper “On the Dynamics of a Collapsing Stack of Blocks”, coauthored with Theresa Honein we use a generalized alpha numerical method developed by Capobianco et al [1] to simulate the collapse. The examples we consider include the Leaning Tower of Lyre and the collapse of a stack of blocks that is produced by harmonic excitation of a foundation.
Dear Colleagues,
I am sharing a recent paper titled "Designing Physicochemically‐Ordered Interphases for High‐Performance Composites" published in Advanced Functional Materials. Here is the link to the paper: https://doi.org/10.1002/adfm.202502972
I am happy to share our recent paper published in Cell Reports Physical Science: Inhomogeneous substrate strain-driven long-range cellular patterning
Smart soft materials have gained increasing attention in recent years because of their adaptive behaviors to external multi-physics stimuli, enabling diverse applications across multiple fields. Here, we show programmable wrinkling morphological patterns on liquid crystal network (LCN) bilayers bonded to compliant substrates under thermal load, by tuning the orientation of directors between LCN bilayers. We propose a solid-shell formulation that merges enhanced and natural assumed strain approaches to investigate the pattern formation and morphological transition of LCN bilayers.
