Analysis Type(s): Linear Static Structural Analysis
Element Type(s): Beam and Shell

Test Case

A mixed model (shell and beam) has one shell edge fixed as shown below. Bending loads are applied on the free vertex of the beam as given below. Apply a global element size of 80 mm to get accurate results.

  • Scenario 1: Only a force load.

  • Scenario 2: Only a moment load.

Find the deformation in the y direction under Solution Combination with the coefficients for both the environments set to 1.
