research

Hi all,

I have a strange question that has puzzled me since last almost one year.

There are many SG-plasticity models in the technical literature, sometimes categorized as lower-order or higher-order models.

The problem is :

the constitutive models include the gradient of plastic parameters (e.g. plastic slip).

Hi,

In my research i am trying to develop a new model for plastic deformation, and i suspect there is a strong similarity between

plasticity and turbulent flow !.

My question is: if there is workd done trying to apply Reynolds decomposition (Reynolds Stress) to the governing equations and solved plasticity problem in Solids?

thanks,

Yaron B.S.

Bistable structures, exemplified
by the Venus flytrap and slap bracelets, can switch between different
functional shapes upon actuation, and have important applications in
mechanical/electro-mechanical devices ranging from bio-inspired robots to
deployable aeroplane wings. Despite numerous efforts in modeling such large
deformation of shell structures, the roles of mechanical and nonlinear geometric
effects on bistability remains elusive. Closely related, emerging challenges
include modeling the spontaneous curving and buckling of thin objects such as
