Project 1 - Impact of Ball on Wall

Objective:

Simulation of rigid ball impacting on a non-linear aluminium alloy plate.

Mesh the model and assign the contact properties.

Find the total deformation.

Procedure:

Using explicit Dynamics the impact analysis in done for three given different velocities.

CASE 1:

The velocity component in Y direction is given as 50m/s.

The corresponding deformation the above given is as follows.

The maximum deformation due the impact of the rigid ball is 0.11322mm.

Therefore its concluded that there is no rupture or very less indentation on the plate.

CASE 2:

Here the given velocity is 250m/s.

Here te maximum deformation is 4.2142mm whereas the thickness of given plate is 5mm.

Eventhough there occurs huge deformation but still there is rupturing the plate.

CASE 3:

The initial velocity in this case is 500m/s.

In this case the maximum deformation is shown as 12.09mm which in sure indent the plate and rupture takes place.

Result:

The velocity at which the plate gets ruptured is 500m/s.
