Author's Biography

Denver Seely studied electrical and mechanical engineering at Cedarville University earning a B.S.E.E. in 1999. He earned a M.S. degree in bioengineering from the University of Toledo in 2000. Denver studied astro/geophysics at the Institute for Creation Research graduate school (2005) and worked as facilities engineer at the AiG Creation Museum (2006-2008). He earned a Ph.D. in mechanical engineering at Mississippi State University (2018) researching metal layered composites and functionally graded materials using laser based 3D metal printing systems.

Andrew Bowman studied biology and engineering at Mississippi State University earning his B.A. in biological sciences in 2012 and his B.A. in mechanical engineering in 2014. Currently, he is a Ph.D. student in Mechanical Engineering at Mississippi State University conducting research in the area of multiscale modeling and computational engineering of viscoelastic materials.

Noah Cho is currently a Ph.D. student in computational engineering at Mississippi State University, with an emphasis on computational geophysics. His dissertation research involves development of improved numerical models for the deformation behavior of mantle, combined with an exploration of how that deformation behavior influences the earth’s dynamics. The goal of his work is to model the plate tectonics during the Genesis Flood in a more realistic manner than ever before and to gain deeper insight into the physical processes that occurred during this cataclysm.

Mark Horstemeyer is a fellow of four societies (ASME, ASM, SAE, and AAAS), is a member of the European Union Academy of Sciences and has garnered international acclaim as he has published over 500 journal articles, conference papers, books, and technical reports with a citation impact h-factor of 52; he has given 150 lectures throughout the world (was named as honorary professor of Xihua University, Chengdu, China); and has won many awards (R&D 100 Award, AFS Best Paper Award, Sandia Award for Excellence, Ralph E. Powe Research Award, Ohio State’s Thomas French Alumni Achievement Award); and has mentored over 120 graduate students and post-doctoral researchers.

Abstract

Finite element simulations of near impacts of terrestrial bodies are presented to investigate possible deformation behavior induced by a massive body during the creation week and/or Genesis Flood. Using the universal law of gravitation, a gravitationally loaded objected is subjected to the ‘pull’ of a near passing fly-by object, and the resulting surface deformations are studied. An Internal State Variable (ISV) pressure dependent plasticity model for silicate rocks (Cho et al., 2018) is used to model the deformation behavior and to capture the history effects involved during the complex surface loading/unloading found in a near impact event. The model is used to simulate the earth and a “fly-by” object interaction and is able to accurately reproduce the internal pressure profiles of the earth and fly-by object. In this context, the fly-by object can be the original Moon, a meteor, or another type of large object that has moved through space to interact with the Earth. Due to the wide range of features that can drive surface deformations during a near impact event, a Design Of Experiments (DOE) methodology was used to independently investigate the influences of five parameters (stationary body size, core material, core/mantle thickness ratio, passing object mass, and passing object distance) concerning surface deformation. The results indicate that the passing body distance, stationary body size, and core/mantle ratio are the most dominant influence parameters on surface deformation. Examination of the ISV parameters of the mantle during deformation shows a complex relationship between the hardening and recovery terms of the model and the resulting plastic strain and surface deformation induced from the near pass event. Surface rise from the near passage of a Moon sized object could be as high as 800 m, in turn causing large tsunamis and possibly causing the Earth’s crust to crack. For this first of its kind study, the conclusions provide understanding of the possible ranges of deformations observed from a near pass event and provides insights into possible catastrophic deformation mechanisms relevant to the young Earth paradigm.
