Transient Cytoskeletal Anisotropy Encodes Short‐Term Mechanical Memory in Glioblastoma Cells

Advanced Materials, EarlyView.
The same mechanical deformation can produce distinct cytoskeletal states depending on loading history. Experiments and constitutive modeling reveal that transient actin–vimentin anisotropy stores mechanical information and governs short‐term mechanical memory in glioblastoma cells.

Flax Composites With Improved Interfacial Strength Through Microbially Induced Mineral Precipitation

Advanced Materials, EarlyView.
A bio‐inspired biomineralization strategy introduces an additional hierarchy to flax fiber composites. By controlling microbe‐mediated mineral particle deposition through tuned salt concentrations, stress transfer within the natural fiber composite is enhanced.

Mechanically Assisted Magnetic Actuation in Ceramic‐Based Microscrolls for Fast and Durable Soft Robotic Systems

Advanced Materials, EarlyView.
Ceramic‐based V2O5/Fe3O4 hybrid films are shaped into butterfly‐proboscis‐inspired microscroll actuators. Magnetic triggering initiates unrolling, while geometry‐programmed elastic strain energy drives rapid recoil, enabling fast, reversible, durable, and load‐bearing actuation under near‐field magnetic stimulation.

Large-scale buckling-constrained topology optimization based on assembly-free finite element analysis

Advances in Mechanical Engineering, 2017
In this article, we propose a fast method to solve large-scale three-dimensional topology optimization problems subject to buckling constraints. Buckling analysis entails the solution of a generalized eigenvalue problem.

Micropillar‐Engineered Hybrid Adhesive Patch for Surface‐Conformable and Directional Adhesion

Advanced Materials Technologies, EarlyView.
This work presents a surface‐conformable hybrid adhesive integrating height‐optimized hexagonal micropillars with open‐rectangular cuts. The micropillars enhance rough‐surface contact and microscale crack arrest, while the cuts guide and reverse interfacial cracks for strong and directional adhesion. The multiscale architecture achieves robust pull‐off

Fabrication of Fibers With Complex Features Using Thermal Drawing of 3D‐Printed Preforms

Advanced Materials Technologies, EarlyView.
3D printing enables rapid fabrication of macroscale polymer preforms with complex geometries. Thermal drawing then scales these structures into long fibers while preserving micron‐scale cross‐sectional features. This workflow provides a fast, low‐cost route to functional fibers with tailored geometries and material combinations for catheter, robotic ...

Buckling load of bending coiled tubing under an injector

Advances in Mechanical Engineering, 2018
When coiled tubing is applied in high oil–gas wells, buckling load of a coiled tubing under the injector is the key for functionality. The coiled tubing is curved, but it is simplified to straight tubing for buckling load solved in the past.

Strain‐Activated Mechanical Metamaterial With Programmable Dual‐Phase Stiffness and Enhanced Energy Absorption

Advanced Materials Technologies, EarlyView.
A strain‐activated mechanical metamaterial is developed to achieve programmable dual‐phase stiffness through an intrinsic geometric locking mechanism. Finite element modeling and parametric analysis identify the key design parameters governing activation strain, stiffness transition, and energy absorption.

Elimination of Necking and Aspect Ratio Dependence in Uniaxial Actuators by Continuous Fiber Reinforcement

Advanced Robotics Research, EarlyView.
A novel carbon fiber reinforcement for dielectric elastomer actuators enhances actuation force while decoupling electromechanical performance from the actuator's aspect ratio. Unlike conventional fiber reinforcements, it enables a uniform planar stretch state along the entire actuator.
