Project 1 - Impact of Ball on Wall

Project 1: Impact of Ball on Wall

Aim: Simulating ball impact on wall using Ansys Workbench explicit Dynamics.

Case1: Velocity of ball is 50m/s

Case2: Velocity of ball is 250m/s

Case3: Velocity of ball is 500m/s

Procedure:

Intially the Explicit Dynamics system is loaded in workbench.

Engineering materials used for this model:

Ball material:

Plate Material:

The model is created in Ansys Spaceclaim

Intially the rectangle of 100x100mm is created in a plane.

The using Pull the rectangle surface is extruded by 5mm

Then a sphere of diameter of 10mm is created and it is shifted to a corner of the plate created and moved by 20 in y, 50 in x and 50 in z axis directions

1. After model is creeated, the model's setup and solution is done in mechanical modeler.

Here, meshing, contacts, boundary condition setup, and solution output request are given for analysis.

Meshing:

Meshing is done to plate by sizing

Analysis Settings:

For the three different velocities the end time is changed to optimize the computational time.

Case1: 50m/s velocity

Case 2: 250m/s velocity

Case 3: 500m/s velocity

Boundary Conditions:

Intial velocity on ball is applied with components

Plate four sides are fixed

Case1: Intial velocity is applied on Ball: -50000mm/s

Case2: Intial velocity is applied on Ball: -250000mm/s

Case3: Intial velocity is applied on Ball: -500000mm/s

1. Solution output request

After setting the boundary conditions, the soultion outputs as requested is included from

Only for Case 1:

solution -> insert -> Stress -> equivalent von mises

solution -> insert -> Deformation -> Total deformation

Results:

The solving is taken place and can be checked from

The results are taken for Stress and deformation for both cases

Equivalent stress:

Case 1:velocity of 50m/s

Case 2: velocity of 250m/s

Case 3: velocity of 500m/s

Comparing the maximum stress, we can see for velocity of 50m/s only has some elements beyond the yield stress and for 250m/s none of the elements have reached ultimate strength of 500MPa.

Only the velocity of 500m/s has some elements failing and plate is not completely ruptured.

Total deformation:

Case 1: velocity of 50m/s

Case 2: velocity of 250m/s

Case 3: velocity of 500m/s

Conclusion:

Simulation of ball impact on the plate is successfully simulated using ANSYS WORKBENCH.
