  Hello,
  
  I am using the student license of Workbench 2019 R3 and Mechanical to complete research modelling the deformation of a hole in a thin member in tension. The main goal is to determine the change in circumference (or edge length) of the circle embedded in the member after a load is applied. I have implemented the total deformation probe to the edge of the hole and received answers on the order I was expecting. Does anyone know if the deformation probe will produce a valid change in length of this edge within a member in tension? Also, how does the total deformation probe produce the values it outputs? Does it measure the displacement of a specific number of points in whichever direction they are deforming?
  
  Thank you for the help,

  Hello Keegan,
  
  The deformation probe will give the maximum value of the deformation, among all the nodes on the edge you have selected (or whichever entity you have selected). So in this case, it won't give the change in circumference of the hole. A workaround this could be to create another static structural system in Workbench and drag and drop the Solution of this problem to the Model of that Static Structural system. The deformed shape will be the starting geometry in the new Static Structural system. Then in the new model, if you use Edge Selection and select the circumference of the hole, on the bottom right corner you should be able to get the circumference of the deformed hole.
  
  You should then be able to subtract the obtained value from its original circumference to get the change.
  
  Then in the new model, if you use Edge Selection and select the circumference of the hole, on the bottom right corner you should be able to get the circumference of the deformed hole.
  
  About your question: Does it measure the displacement of a specific number of points in whichever direction they are deforming?
  
  When defining the deformation probe, you define the Result Selection. So based on whether a direction (x or y or z-axis) is chosen for the Result Selection or whether it is Total, the Deformation probe will measure either directional or total displacement of the nodes in the selected entity and report the maximum value from that set.
  
  Hope this helps.
