VMR049-PL5
Pressurised Cylinder Plasticity Benchmark

Test Description

A square of length R2-R1 and height H is constrained in the Z-direction on the top and bottom edges and offset a distance R1 from the origin. A distributed pressure load is applied to the left edge.

Geometric Properties (Axisymmetric)
R1 = 100 mm
R2 = 200 mm
H = 100 mm
Material Properties
E = 21.0 x 103 N/mm2
ν = 0.3
Plasticity Model
Perfect Plasticity: σys = 24.0 N/mm2
Isotropic Hardening: ET = 4.2 x 103 N/mm2
Boundary Conditions
Top and Bottom Edges: uz = 0
Loading
Internal pressure, P, at the bore (left edge) applied in 4 steps.
Step: Perfect PlasticityStep: Iso. Hardening
1: P = 10.0 N/mm21: P = 10.0 N/mm2
2: P = 14.0 N/mm22: P = 14.0 N/mm2
3: P = 16.6 N/mm23: P = 24.0 N/mm2
4: P = 19.2 N/mm24: P = 34.0 N/mm2

Results

Reference: Stress results are displayed for each step as the step is incremented by 1 starting at 0 and ending at 4.
