[SEAOC] Re: [SEAOC] [Q:] Explosion wave ---> Damping?

[Subject Prev][Subject Next][Thread Prev][Thread Next]
In that type of explosive (impulsive) loading I don't think damping has much
influence.  The load is usually short duration and of high value.  You are
most probably interested on the peak response in which case damping won't
make much difference.  In most cases damping is ignored under impulsive loads.
