ist there any way to evaluate the stress component normal to a curved imprinted edge or path without defining local cylindrical coordinate systems for each radius of the imprinted edges?
Hello @lbhhop1 ,
You can get the stress component normal to the surface by always creating the local co-ordinate system and setting one of the axes normal to the given surface. This is the most preferred and easy way. Even the local co-ordinate systems can be generated using object generator.
The following are the links for the discussions on the same line-

Since, you want a method other than the local coordinate system method,
You might want to try the method in which strain is analyzed using a strain gauge (Single element meshed surface with zero stiffness and minimal thickness created at the locations of interest.)Instead of asking strain as output, you can ask stress in the particular direction as the output.
The following steps might guide you for the same-
