VMR049-CR1
Constant-Load Creep Benchmark

Test Description

A 2D box of length L and height L is constrained at left edge in Y-direction and in both X and Y directions at midpoint. A distributed load, σ, is applied on the right edge.

Geometric PropertiesMaterial PropertiesLoading
L = 100 mm
Boundary Conditions
Left End: ux = 0
Left End Midpoint: uy = 0
E = 200 x 103 N/mm 2
ν = 0.3
Secondary Creep: ε = Aσntm
A = 3.125 x 10-14 (t in hours, σ in N/mm2)
m = 1, n = 5
Primary Creep: As Secondary Creep, except m = 0.5
Combined Primary-Secondary Creep:
ε A1σn1t + A2σn2tm
A1 = 10-16
A2 =10-14 (t in hour,σ in N/mm2)
n1 = n2 = 5
σ = 200 N/mm2 (Secondary Creep and Primary Creep)
σ = 100 N/mm 2 (Combined Primary-Secondary Creep)

Results

Reference: Creep strain results are displayed at intervals of 200 ending at 1000.
