Riassunto analitico
A series of simulation tests on thin-walled tubes. The models have been created at identical radius and thickness. Different shapes of the triggers, which are lobe0, lobe3 and lobe4, are provided at the impact side of the tubes. According to Norman jones's theories, calculate the theoretical value, and then set the simulation parameters of theoretical value. After the first phase of the simulations, the length of models is doubled and the test is performed with triggers which are in different modes and different sides. Ensuring that kinetic energy is equal to the case, change the velocity of impact, once again for comparison.
