High resolution adaptive framework for fast transient fluid-structure interaction with interfaces and structural failure - Application to failing tanks under impact

A high-resolution computational framework combining accuracy and robustness through generic mesh adaptivity is proposed and fully described in the present paper, to provide advanced numerical results related to the response of fluid-structure systems under impact, with fluid interfaces and potential structural failures. The numerical characteristics of the coupled scheme are extensively analyzed through a parametric study based on a significant 3D test and it is then confronted against complex experiments with very satisfactory validation results.
