VMR049-CR2
Constant-Displacement Creep Benchmark

Test Description

A box of length L and height L (and thickness L if 3D) is constrained in the Y-direction along the bottom edge and in the X-direction along the left edge. The box is displaced in all directions by a set amount.

Geometric Properties

Material Properties

L = 100 mm

Boundary Conditions

2D Plane Stress

Left Edge: u_x = 0, Right Edge: u_x = 0.1

Top Edge: u_y = 0.1, Bottom Edge: u_y = 0

Left Face: u_x = 0, Right Face: u_x = 0.3

Top Face: u_y = 0.2, Bottom Face: u_y = 0

Front Face: u_z = 0, Back Face: u_z = 0.1

E = 200 x 10³ N/mm²

ν = 0.3

Creep Law: ε = Aσⁿt^m

A = 3.125x10^-14 (t in hours, σ in N/mm²)

n = 5

2D Plane Stress: m = 0.5

3D: m = 1

No applied forces

Results

Reference: Stress results are displayed at incremented time intervals of 200 hours ending at 1000 hours
