1. Reference problem#

1.1. Geometry#

It is a material point, representative of a state of homogeneous stresses and deformations.

1.2. Material properties#

They come from test SSNL129 [V6.02.129]

Isotropic elasticity

1.3. Boundary conditions and loads#

The load is in imposed deformations along the \(y\) axis, corresponding to speeds \(\dot{\varepsilon }\) of \({10}^{-3}{s}^{-1}\)

\({\varepsilon }_{\mathrm{yy}}=0.2\) for \(T=2000s\), in 100 increments.

All other components of the deformation are zero.

1.4. Initial conditions#

Zero stresses and deformations at \(t=0\).
