Model

A cubic solid body is created. The material is rutile which has the anisotropic elasticity.

The anisotropic axis is oriented to (1, 1, 1), which is set on the direction tab of the body attribute.

The compressive pressure is set by the outer boundary condition.

Body Attributes and Materials

Body Number/Type	Body Attribute Name	Material Name
0/Solid	CUBIC	201_Rutile *

* Available from the material DB

 

Body Attribute Name	Direction
CUBIC	Vector Specified: Vector: X=1.0, Y=1.0, Z=1.0

The matrix indicates that the 3-3 direction has the highest elasticity. Therefore, it is set to be (X, Y, Z)=(1, 1, 1).

Results

The vectors of displacement are shown below.

 

The displacement is shown below. The contour indicates the magnitude of displacement.

(X, Y, Z)=(1, 1, 1) exhibits the lowest compressive displacement.

 

The vectors of internal stress are shown below.

The pressure is applied uniformly, hence the internal stress is -1 [MPa] uniformly.
