VMR049-CR4
Pressurised Cylinder Creep Benchmark

Test Description

A box of length R₂-R₁ and height H is offset from the origin by a distance R₁. The bottom and top edge is constrained in the Y-direction and a distributed load, P, is applied to the left edge.

Geometric Properties

Material Properties

R₁ = 100 mm

R₂ = 200 mm

H = 25 mm

P = 200 N/mm²

Boundary Conditions

Bottom and Top Edge: u_z = 0

E = 200 x 10³ N/mm²

ν = 0.3

Creep Law: ε = Aσⁿt^m

A = 3.125 x 10^-14 (t in hours, σ in N/mm²)

n = 5

m = 1

Pressure, P, applied to left edge.

Results

Reference: The elastic and steady-state radial and hoop stresses obtained from MAPDL are compared against reference for radius starting from 100mm to 200mm at an increment level of 25.
