Deformation kinematics during the impact of a ball on a bar. This application provides a solution for Hertzian contact theory for the impact of a solid sphere against a solid bar. The solution is provided following a nonlinear differential equation governs the stress pulse created in the bar. The code is written in MATLAB. The user interface was developed using MATLAB's App Designer interface.
Note: Requires Symbolic Math Toolbox to Perform symbolic math computations downloadble from Matlab toolbox section.
ρ = Density (kg/m3)
R = Radius of bar (m)
C = Speed of stress wave (m/s)
E1 = Young's Modulus of bar material (N/m2)
v1 = Poissons ratio of bar material
t = Charateristic time/cycle time (s)
r = radius of material (m)
E2 = Young's Modulus of ball material (N/m2)
v2 = Poissons ratio of ball material
