The calculations in the demo are all performed in your browser (the front-end). This takes longer on slower devices like mobile phones.
The full version can calculate both in front- and in back-end.
The simulation is caried out up to a creep strain of 5%. This is approximately the deformation at which many workpieces fail.
Go to the next tab in the tutorial to see what you can do here...
Below this text there are some controls and a diagram with the title "Creep curve". If you hit "plot"
a simulation will be started and the result will be immediately displayed in the diagram.
If a check mark is set at "automatic replot" the simulation will be started whenever you change
the values of the controls.
The button "reset" sets the controls back to the start values and also stops a running simulation.
You can increase or decrease the temperature by 1°C (in most browsers by clicking on the arrow up or down at the right
of the temperature control).
You can observe that a small change in temperature has a huge effect on the durability of a workpiece.
Changing the applied stress by one megapascal has a similar effect.
Now try moving the slide control below ρm,0 (the mobile dislocation density at start) to the left or the right (the control has a logarithmic scale).
Decreasing the value to a minimum suppresses the primary creep stage, increasing it makes it more pronounced.
Please note that this controls the value at start. The mobile dislocation density changes later during the creep process.
