In SEM images of the sintered co-doped BT ceramics the strips are appeared. I want to know what is the reason behind that?

From the attached image it is appear that some strips is taken place i want to know about that what is the reason?

In the paper: Fabrication of Perovskite Barium Titanate Ceramics Using the Combustion Route by Perapong Panya and Theerachai Bongkarn, available on RG is available a SEM image of PBT sintered at 13500C which shows grains with similar surface strips as in your case.

How to define an anisotropic material with asymmetric elastic compliance/stiffness matrix in ANSYS APDL?

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...
