The contours and grooves on the NIKE Strike Soccer Ball give it a unique surface that is textured and designed for ball handling. 6 color patterns and 3 different sizes make it a ‘jack of all trades’ ball that can entertain any age group. The power graphic adorning the side with the signature swoosh makes tracking the ball a breeze no matter how fast it is moving.
Elements of the football that today are tested are the deformation of the football when it is kicked or when the ball hits a surface. Two styles of footballs have been tested by the Sports Technology Research Group of Wolfson School of Mechanical and Manufacturing Engineering in Loughborough University; these two models are called the Basic FE model and the Developed FE model of the football. The basic model considered the ball as being a spherical shell with isotropic material properties. The developed model also utilised isotropic material properties but included an additional stiffer stitching seam region.
