ANALYSIS OF SPHERE PRESSING ON A PLATE

Objective :

To perform a static structural analysis of sphere pressing on a plate
And to find out its plastic deformation.

Geometry :

Given geometry is imported in static structural.

Materials :

• Structural steel - sphere
• Structural steel NL - plate

Symmetry :

The original geometry is shown in figure.

It\'s a symmetric model. So, to reduce the computational time 1/4 the from the origal model is taken and symmetry is applied to corresponding direction.

Contacts :

frictional contact with value of 0.74 were created between, target which is plate and contact which is phere created.

friction value refered from roymech friction values.

Mesh :

Mesh size of 1 mm generated to each body.

Analysis setings :

Fixed support :

The downside of the plate is fixed by using the fixed support.

Displacement :

4mm displacement were created to the sphere

Result :

from the simulation, when the sphere return to its original position, the plate remains deformed shape, so its is plastic deformation.
