Mathematical Improvements for Naval Simulations
Abstract
The proposed research will address nite element modeling problems in vibro-acoustic prob- lems of complex structures. The main focus of the proposed research is on understanding of the numerical di culties associated with increasing the numerical delity of the nite element models through addition of geometric and structural details. Consistency of the computed re- sults and their agreement with the measured data under the model re nement by using various types of nite elements will be examined through analytical and numerical investigation. The goal of the proposed research is to examine and quantify errors in nite element models of complex structures exposed to external periodic forcing. The best practice guidelines for modeling of structures will be created using the obtained through quantitative understanding. The best practice recommendations will be created in the form of dimensionless numbers and parameters associated ith the type of nite elements used to model structural parts. The dimensionless numbers and parameters will guide nite element practitioners in their use of lower or higher order nite elements in a systematic way so that the consistent results are possible to compute using models with more geometric and structural details. The project will take place over the period of 3 years starting in July 2015 and ending in July 2018.
