7.3.1.4 Loop1 Module
The Loop module is to control the shot impact sequence until the maximum
number of shots is satisfied. It counts from two to the number of shots on the
simulated area. The output of this module is called [I1] and its function can be seen
in the MATLAB code listed above.
7.3.1.5 ABAQUS Static Step Analysis
The final result of the explicit finite element simulation of shot peen is followed by
a static step analysis to estimate the final stresses and deformations.
7.3.2 Test Case-1
A single shot of a sphere of 0.97 mm radius at 31 m/s on a cylindrical plate
(R 10 mm, H = 4 mm). The meshed finite element model is shown in Fig.
