A new continuum model for metallic glass based on thermodynamics

Submitted by Xiaoding Wei on

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.

contact not working

Submitted by jumar on

Hello

im trying to model a pin on disk wear using a *STEADY STATE TRANSPORT, INERTIA=YES as i understand i have to create a axysimmetric 2d model an then rotate it using the *SYMMETRIC MODEL GENERATION,REVOLVE,ELEMENT=1000,NODE=1000 in a secind file.

On that second file im defining the pin as a an analytic surface and defining the contact, but when i run the model the pin just go trought the disk.

Atached you can found the axisimetric model and the revolution model. 

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.

VUMAT viscoelasticity (Maxwell model)

Submitted by surot on

Dear all,

I would like to ask you for advice. I am about to simulate a pull-through test (see attached picture) of a cladding panel made of a material with highly viscoelastic behaviour. I have parameters for Maxwell model (Prony series) obtained from test. I expect large deformation and probably cone failure (or tearing of the cladding panel). Therefore I would like to use Abaqus/Explicit. The problem is that I cannot use *visco step together with Explicit. Is there any way to solve it?
