Total Deformation representation problem

Subscriber

Hello everyone,

I am doing a simulation of penetration of a robot driller into the Plaque. I applied remote displacement on the robot in Z direction and Z-rotation direction using tabular data. As you can see in Equivalent stress the color scheme representation of the stresses is logical, when the robot is still away from the plaque there are no stresses and when the robot touches the plaque the stresses starts to appear at the tip of the robot as you can see in the next 2 photos.

Total Deformation is the distance the node moved from where it started. As the drill rotates, the nodes on the OD of the back of the drill move in a circle and obviously move a lot further from their starting location than the node on the tip that is on the centerline and rotates in place.
You are confusing Total Deformation with Strain. Strain is the relative displacement of the nodes within the element and strain will plot just like stress because they are related.
