How to calculate absorbed energy in a material during impact?
How to calculate absorbed energy in a material during impact?
(OP)
Hi,
I have a hollow tube is being impacted by a block of 25 kg at 14 m/sec along its longitudinal axis.
I am using INT_ENERGYALL results option in ANSYS Explicit and I've selected the tube as my body.
The problem is: the calculated result is way too high - (1.13 e5 J/kg)~ 11515 J for the 0.108 kg tube - compared to the 0.5*m*v^2= 2450 J initial kinetic energy.
Any thoughts?

(internal, kinetic, hourglass, contact) during solution cycles? Are they making sense?

simply multiply it by the total mass of tube to get total internal energy of the tube.

How then to derive the absorbed energy from ANSYS?
Thanks
