Hypothesis: The goal of this research is to test the hypothesis of tensile testing of material through rare experiment versus tensile testing through computer simulation. This is vital information in evaluating the strength of materials used in manufacturing processes. Methods and Control: First, a material sample dog-bone was designed in Siemen’s NX CAD under realistic parameters and measurements. Second, with the sample already modeled in NX, the model will be imported into the simulation system, NX Nastran, to be set up with a preprocessor, boundary conditions and the material. A simulation of the sample model will be run, results will be recorded and the postprocessor will be set up. Meanwhile, a tensile test will be conducted in the manufacturing lab to determine the strength of the material, yielding point, ultimate tensile strength and fracture point. The results of the simulation in NX Nastran will be compared to the results of the tensile test conducted in the manufacturing lab. This will be concluded with an error analysis. Results: Aiming for results to reveal a decisive superior strategy between tensile testing and simulation analysis. The superior strategy will be decided upon how large of a difference between the results of the two strategies. Conclusion and Future Research Direction: Tensile testing has proven to be a very valuable asset in determining which materials to use in manufacturing processes. The current material being tested is a simplistic material. Would hope to conduct simulation analysis on more complex parts such a heart pump and an impeller in future research.
