Determination of domain A for interaction integral
Can anybody tell me in determining the SIF using domain form, How can I determine the domain A and what are the factors which determines the radius rd about crack tip for the determination of domain A.
Hi Awais, Usually, domain
Hi Awais,
Usually, domain A is a set of elements within a circle centerd at the crack tip and have radius of 3 * area of the element containing the tip. As you know, the interaction integral is independent, so just use quite large factor (3-5) is ok.
Hope it helped.
