Moose Solving Dynamic Solid Mechanics Problem

[Max]

Hi,

I am wondering is the current version of Moose has the capability of solving a dynamic solid mechanics (with inertia effect) problem ? 

Basically just simple :

rho*u_dot_dot=Div(sigma)+f

Using either explicit or implicit time integration scheme. 

And if there is an example about this ? Using newark or HHT, or just simple explicit Euler? 

Thank you , 

Max

Pinging a few solid mechanics guys to see if they could address this question.

There is no explicit dynamics for solid mechanics, but Moose does have implicit dynamics.  See:

Thanks,

Thank you , so you mean moose doesn't have an explicit solve , such as explicit-euler, or central difference   in Tensor mechanics ?
