the problem with metal to rubber bond lines using fea is the solution for the rubber and the solution for the metal material are smeared together at the bond line(nodes) giving incorrect results. The bondline strain of the rubber at the bond line is the result of interest. ADINA software by...
using the Odgen material model , you need three differnt types of load vs stretch data for 3D models and only two types of load vs stretch data for 2D models.
1. tension-compression
2. simple shear
3. pure shear
The odgen model is quite complex but characterizes the rubber material better than...
I do stepped gear shafts on aircraft actuators.
model the shaft 3D using small angle of rotation say 5 or 10 degrees, set the coordinate system to cylindrical, do an "nrotate", all" command
apply symmetical BC on cut surfaces, isolate line, select nodes attached to line, make...
