Benchmark Model
Quad8 elements are used to create a mesh on the cylindrical patch with 4 elements for the load case 1 and Quad4 elements are used to create a mesh with 16 elements for the load case 2. All the translations and rotations are constrained at edge AB, z-translation and normal rotations are constrained at the edges AD and BC. For Load case 1 a uniform normal edge moment of 1.0 kNm/m is applied on the edge DC and for the Load case 2, uniform outward normal pressure of 0.6 MPa is applied on the mid surface ABCD and a tangential outward normal pressure of 60.0 MPa is applied on edge DC.
