A question about electric displacement intensity factor of interacting cracks in piezoelectric materials
I am working on the problem of interacting cracks in piezoelectric materials. Due to the interaction of cracks, I found a non-intuitive phenomenon that the electric displacement intensity factor of the crack for some interacting profiles may be negative under some loading conditions (a tensile stress and an applied electric displacement). However, under the same loading conditions, the electric displacement intensity factor can never be negative for a single crack problem.

cracking analysis OF a 3-points bended sandwich beam in the negative stressed area of the beam (above the neutral axis)
Hi,all
I'm looking for ideas-ways to model the above mentioned thema and solutions to overcome some obstacles. Here are some observations of mine:
1) Above the neutral axis of a bended beam the stress field is negative.Furthermore the traditional type of K factors estimation in Ansys is insufficient.The reason as i believe is that we haven't relative despacements of the crack nodes along y(normal) axis.In contradiction we have shear desplacements.So i retrieve Ki nearly zero and Kii some noticable results.(using contact elements)
