This is a very basic question but I will be happy if someone can help me here.I had been reading about Hourglassing as I understand (I think I am wrong), hourglassing is that when you have the displacements (or the field variable)at integration points '0'.If this occurs it would result in 0 displacements at nodes as well (because displaceemnts from interpoaltion pioints are extrapolated at nodes) which is incorrect.Can anyone please explain in simplest manner about hourglassing?I shall be very grateful.
Please can anyone help?
