Covariantization of Nonlinear Elasticity

Submitted by arash_yavari on

In this paper we make a connection between covariant elasticity based on covariance of energy balance and Lagrangian field theory of elasticity with two background metrics. We use Kuchar's idea of reparametrization of field theories and make elasticity generally covariant by introducing a "covariance field", which is a time-independent spatial diffeomorphism. We define a modified action for parameterized elasticity and show that the Doyle-Ericksen formula and spatial homogeneity of the Lagrangian density are among its Euler-Lagrange (EL) equations.

ABAQUS/CAE

Dear All,

I am going to draw a 3-D model to be run in Abaqus. I would like to know how I can do that.

I find it is a little bit cumplicated to design the 3-D structure with certain curvatures in CAE. 

Could anyone tell any assisting softwares or approaches of designing the 3-D geometry in a simpler way for finite element analysis?

 

Many thanks,

 

Jay
