Problem Description: Vases are decorative pieces that can be of any artistic shapes. The
figure below gives the dimensions of a flower vase made of glass. Assume that the vase
has a uniform thickness of 4 mm. The water level reaches 100 mm below the opening of
the vase. Determine the maximum deformation and von Mises stress in the vase under
the hydrostatic pressure.

80 mm
Material: Glass

E = 70 GPa
E = 0.17

Boundary Conditions:
D Bottom surface: fixed.
280 mm Coordinates of Construction Points:

C A: (50 mm, 0 mm, 0 mm)

B: (90 mm, 40 mm, 0 mm)
B
C: (60 mm, 120 mm, 0 mm)
A D: (40 mm, 180 mm, 0 mm)
50 mm E: (80 mm, 280 mm, 0 mm)

Solution
To solve the problem with ANSYS Workbench, we employ the following steps:

Step 1: Start an ANSYS Workbench Project
Launch ANSYS Workbench and save the blank project as ‘Vase.wbpj’.
Step 2: Create a Static Structural Analysis System
Drag the Static Structural icon from the Analysis Systems Toolbox window
and drop it inside the highlighted green rectangle in the Project Schematic
window to create a standalone static structural analysis system.
