Super-stretchable, skin-mountable, and ultra-soft strain sensors are presented by using carbon nanotube percolation network–silicone rubber nanocomposite thin films. The applicability of the
strain sensors as epidermal electronic systems, in which mechanical compliance like human skin and high stretchability (e > 100%) are required, has been explored. The sensitivity of the strain

In an article published in the August 20 issue of Nature Communications, we report a mechanochemical phenomenon in graphene oxide membranes, covalent epoxide-to-ether functional group transformations that deviate from epoxide ring-opening reactions, discovered through nanomechanical experiments and density functional-based tight binding calculations.

Solution-Dependent State Variables Defined in Subroutine FRIC Cannot be Displayed in ABAQUS Visualization Module

Hi,

 

I am now using ABAQUS subroutine FRIC to define some solution-dependent state variables, and I am currently able to check these values throung writing them into a TXT file in the subroutine. However, I cannot find these SDVs displayed in the ABAQUS visualization module although I have already specify them in the Field/History output manager.

 

I will be appreciate if anyone could give me some advice on this.

 

Thanks a lot,

Yi
