Elastic Shell Elements (SHELL63)
8-Node Structural Shell Elements (SHELL93) Input Listing: vmd2.dat Test Case
A cylindrical shell roof is subjected to gravity loading. The roof is supported by walls at each end and is free along
the sides. Monitor the y-displacement and bottom axial stress (σz) at target point 1 along with the bottom circumference stress (σθ) at target point 2 for a series of test cases with varying skew angle β for each element type.
A companion problem that studies uniform element mesh refinement is VMC3. Figure D2.1 Cylindrical Shell Roof Problem Sketch Material Properties
