How to interpret the energy results T01 ( Internal , Kinetic & Total Energy) which is observed in Radioss Explicit dynamic analysis ?
Hi Arul,
The energy balance graph is plotted from the T01 file. The physics of impact involves conservation of energy and momentum. When a moving object strikes a structure the force which decelerates the mass satisfies conservation of momentum.
If the energy is initially set in the model:
• Translational Total Energy (TTE) should be constant or slightly decreasing (loss of energy)
• TTE = IE + KE + RKE + CE + HE
• If energy absorption is the goal then most of the kinematic energy should be transformed to internal energy.
(IE- Internal Energy, KE- Kinetic Energy, RKE-Rotational KE, CE-Contact Energy, HE- Hourglass Energy)
I recommend you to go through our Online Learning Course in RADIOSS Explicit Analysis where all the aspects related to Time History plots are described and also reviewing the energy errors and other parameters are discussed.
