A new continuum model for metallic glass based on thermodynamics

Submitted by Xiaoding Wei on
research

My group at Peking University proposed a novel mechano-chemical continuum model based on the framework of thermodynamics that can describe the microstructural evolution in metallic glass, and connect it with the macroscopic plastic deformation. The model successfully simulated the shear band instability and dilatancy effects of metallic glass under uniaxial tension and simple shear.

Progress report on HASEL artificial muscles

Submitted by Philipp Rothemund on

Dear colleagues,

We have published a progress report on hydraulically amplified self-healing electrostatic (HASEL) artificial muscles in Advanced Materials. In this progress report we report the recent developments of HASEL actuators—including materials, designs, fabrication, and control—and discuss many opportunities for future research.

An all-natural bioinspired structural material for plastic replacement, Guan, Yang, Han, Ling, Yu, Nature Communications, 2020

Novelty/impact/significance:

A strong (stiffness 20 GPa and strength 281 MPa), tough (11.5 MPa m1/2), lightweight (1.7 g/cm3), and thermal-resistant (thermal expansion coefficient 7x10-6K-1) composite material is created, using all-natural raw materials through a mass-producible method.
