Dear experts
i want to check a plate (workpiece) vibration during the cutting process.
so instead of performing the whole cutting process i come to an idea that i simulate the cutting tool as an externel force and i change the material proprties(decreasing them significantly)
for each cutted element during the transient analysis.hence my question is:
is it possible to perform the ofermessioned idea under /transient command in ansys apdl ? and if yes how ?
and is it possible to use Emodif command in /transient solu
Thanks in advance and best regards,
Kouider

thank you so much thats exactly what i was looking for just one more question . is this command can be used along the transient analysis ?
will lose Nothing of trying it . i will use this command to simulate the vibration along a cutting process hope will work
Thank you so much again Claudio Pedrazzi
well itried it using the following code

*endif

Ekill,all

Finish
it works but the problem when i do the animation i saw all elements are aleady exist , i thought Ekill supress the element !!!!!!! but i think not
Claudio Pedrazzi
it works now, i just select from main menu, Entities - Elements - Live Elem's.and now the structures ive without the killed elements
