## Short Circuit

To investigate accuracy, all the models are run for the same displacement input, i.e. they are all compared to the same experiment, which had the characteristics given in Table 4-4.

Figure 4.46: Short circuit results for model A

In each of the experiments, the equivalent predicted results and the percentage deviation from the experimental results are given in Table 4-5. Figure 4.46 and Figure

4.47 show examples of experimental compared with predictions using 'model A' and 'model E' respectively. Model E

Table 4-5 shows both the predicted values and their error as a percentage of the experimental value. Surprisingly, the results do not differentiate between the models.

## Renewable Energy Eco Friendly

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.
