Literature Review: Design Of Experiments In Finite Element Analysis Scoliosis And Spinal Procedure
Design of Experiments (DOE) refers to the way in which a scientific experiment is conducted. By analyzing
five different computer-simulated spinal technique experiments it is clear to see the differences and
similarities between the conducted experiments. Factorial analysis is used to describe the different
techniques and simulations needed for the completion and efficiency of the experiments.
This paper analyzes five different spinal experiments, from an initial 163 studies cited by Dr. Dar, and
compares them to a 60% factor significance average extracted from Dr. Fazilat Dar’s study on Finite
Element Analysis (FEA). Dr. Dar’s paper’s purpose was to examine the different statistical methods used
in FEA, and Factorial Design in particular. Additionally, the study compares the extracted results to a paper
on Data from Factorial Experiments written by Li et al. in 2006, where a 40% significance average was
found. The three methods of factorial analysis that were considered are full factorial, fractional factorial,
and Taguchi designs. Each of these approaches have different ways of determining main interactions and
the significance of events and various factors.
The results of this review showed the efficiency of each of the five studies in terms of DOE. In comparison
to Dr. Fazilat Dar’s paper in 2002, two of the experiments were more efficient and three were less efficient.
On the other hand, when the results are compared to Dr. Li’s paper, three out of five of the papers were
