2D Plane Stress - Stepped Load Primary - Secondary Creep

Test Description

A square of length L and height L is constrained in the X-direction on the left edge and constrained in the Y-direction at the midpoint of the left edge. A distributed load, σ₁, is applied in the X-direction on the right edge.

Geometic Properties

Material Properties

L = 100 mm

Boundary Conditions

Left Edge: u_x = 0

Left Edge (midpoint): u_y = 0

E = 200 x 10³ N/mm²

ν = 0.3

Creep Law:

ε = A₁σ^n₁t + A₂σ^n₂t^m

n₁ = n₂ = 5

m = 0.5

Right Edge:

σ = 100 N/mm² (t = 10000 hrs)

σ = 110 N/mm² (t > 10000 hrs)

Results

Results are tabulated and displayed as in the NAFEMS manual.
