For aerospace vehicles, such as rockets and satellites that are subjected to high mechanical and thermal loading, it is necessary to better understand how the structure is influenced by these loads. Because reducing the mass of the structure while maintaining strength is a very important requirement, field-tested components will be subject to different SFs (safety factors) than those that are only subjected to FEA (Finite Element Analysis). Also to further reduce the magnitude of the load factors in the MOS (Margin of Safety) calculation, mechanical loads are considered to have a different safety factor than the thermal loads. This paper proposes a solution, a tool developed to calculate MOS for structural parts for different safety factors on mechanical and thermal loads, based on data obtained from FEA. The tool takes as input the results from the NASTRAN result files and creates one excel file with MOS for each component requested by the user and different types of summary.
This paper presents a methodology for constructing iterative schemes of any order of convergence for solving nonlinear systems of equations. It also provides formulas for the order of convergence of any iterative schemes constructed using the method proposed in this paper. A test case is conducted numerically for the second and third order of convergence using a computer algebra system called Maxima. The code used is listed at the end of the test case.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
