Three-dimensional parametric analysis of a twin-hulled, submerged, fluid-filled structure subjected to an external shockwave
MetadataShow full item record
This work takes a three-dimensional approach to examining the problem of an external shockwave interacting with a twin-hulled, submerged, fluid-filled structure. The problem will be examined parametrically by using multiple variables including inner and outer shell thickness, internal fluid composition, external shell composition, and distance between shells. The effect that each variable had on the peak stresses and normal displacements seen within the model were examined independently to provide an overview of the problem for potential design considerations, as well as to highlight the power of the three-dimensional model used. Additionally, to justify the additional computational expense of using a three-dimensional model vs a two-dimensional model, comparisons were done with two-dimensional simulations using the same variables to examine to what degree the two methods diverge.
