  • The data calculated by the model is, then, inserted into the correspondent pressure model, allowing to predict the maximum pressure that material can hold;

    To verify whether the model responded to what was expected, the balloon was filled up with air whilst the pressure was measured.

  • Balloon tests provided good results for a initial stage Improvements are already being done based on these tests

    It is possible to come up with new methodologies to test alarge number of fish types and come up with a realisticmetric for determining barotrauma in different countries
