Extreme Mechanics Letters (EML) Special Issue: Call for Paper 

Machine Learning and Mechanics

 

Over the past decade, there has been a growing interest in applying machine learning techniques to problems in mechanics. From material design optimization, manufacturing, to multiscale modelling, to real time prediction and autonomy, data mining and analysis, machine learning techniques have had a massive impact in the field.

apparent paradox: for a sliding flat punch on a viscoelastic halfspace, friction is zero or not?

dear Imechanica friends
 
here is an apparent paradox: for a sliding flat punch on a viscoelastic halfspace, friction is zero or not?  Certainly there seems to be viscoelastic dissipation, but the pressure is also normal to dispacements, so am I missing something obvious here?    Any help is welcome!
 
 
Thanks

A Hidden Convexity in Continuum Mechanics, with application to classical, continuous-time, rate-(in)dependent plasticity

Submitted by Amit Acharya on

Amit Acharya

A methodology for defining variational principles for a class of PDE models from continuum mechanics is demonstrated, and some of its features explored. The scheme is applied to quasi-static and dynamic models of rate-independent and rate-dependent, single crystal plasticity at finite deformation.
