Project Overview
In this example, the impact of a gas-filled ball on a tennis racket is simulated using Abaqus.
The gas inside the ball is modeled using the Fluid Cavity method. The initial mass of the gas is 62 grams, and its initial pressure is 41 kPa.
The main purpose of this simulation is to investigate the behavior of the gas inside the ball and obtain the gas volume and gas pressure during the impact.

Ball and Tennis Racket Model
The ball impacts the strings of the tennis racket with an initial velocity of 6.706 m/s at an angle of 15°.
The ball is modeled as a spherical shell using shell elements. The ball is assumed to be made of rubber and its material behavior is modeled using a hyperelastic material.
The frame of the tennis racket is assumed to be rigid, while the strings are modeled using truss elements.

Initial Tension in the Strings
The strings of the tennis racket are subjected to an initial tension of 44.48 N.
This initial tension produces an initial stress in the strings before the ball impacts the racket.

Gas Pressure and Volume
One of the main objectives of this simulation is to obtain the gas pressure and gas volume during the impact process.
These results can be used to study how the gas inside the ball responds to the deformation of the ball when it impacts the tennis racket strings.
