A shallow cylindrical sheet is subjected to concentrated load at its center as shown in the figure below. The curved edges are free while the straight edges are immovable but allowed to rotate around the edge. It is required to determine the snap-through/snap-back behavior of the sheet. Due to symmetry of the problem, only a quarter of the model is analyzed.
Model Dimensions:
R = 100 in
b = 10 in
θ = 0.10 radians
h (thickness) = 0.25 in
ν = 0.30
P (reference load) = 10 N
The actual dimensions make the sheet look almost like a planar face.
In this lesson, you learn the following:
- Using Arc-Length Control algorithm
- Generating displacement versus load factor graph
