A numerical and experimental approach to characterize the failure modes of hexagonal cell honeycomb core under in-plane loading
(DEStech Publications Inc., 2017-10)In the present study, the failure modes of a hexagonal cell honeycomb core under in-plane loading are investigated. It is shown that, under tensile loading, the node bond failure and ribbon fracture are the main causes of ... -
A brain-inspired framework for evolutionary artificial general intelligence
(Wichita State University, 2020-05)From the medical field to agriculture, from energy to transportation, every industry is going through a revolution by embracing artificial intelligence (AI); nevertheless, AI is still in its infancy when compared to the ... -
A comparative study of time and energy savings due to near field communication technology
(Wichita State University, 2016-04-29)The popularity and demand for the Near Field Communication (NFC) applications are rapidly growing in the recent years. NFC technology helps transfer data by bringing two smart devices closer (5-10 cm). Many important ... -
A comprehensive cost estimation for additive manufacturing
(Wichita State University, 2021-07)Additive Manufacturing (AM) is an emerging manufacturing method by which Computer-Aided Design (CAD) models are directly made into products and structures. Layers of material, such as polymers, metals, ceramics, composites, ... -
A comprehensive iterative design, simulation and finite element analysis of bare metal stent and diseased artery
(Wichita State University, 2015-12)Fatigue is a material failure due to cyclic forces acting upon said material. Fatigue can make the material fail before the stresses reach ultimate tensile strength or fracture strength. Intravascular coronary stent are ... -
A computational methodology for evaluation of the structural damage to a car and its occupant response for the new FMVSS 301R regulation as well as for various real-world rear-end collision scenarios
(Wichita State University, 2017-12)Due to requirements and continuous design improvement in automobile industries, it has become mandatory to keep passenger car and seating in automobile to safest at the time of a crash collisions. Although the rear-end ... -
A computational study of the dynamic responses of a composite versus a metallic aircraft fuselage structure in vertical impact along with examination of inclusion of struts and injury prediction of occupants
(Wichita State University, 2015-07)In recent years, the study on crashworthiness of aircraft fuselage section has been of great interest due to the increase in air travel and demand for occupant safety. The FAA conducted a series of drop tests on aircraft ... -
A computational study on static and unconstrained dynamic rollover crash tests of a mid-size SUV for various initial rollover parameters
(Wichita State University, 2018-05)In terms of frequency of accidents, rollover crashes are uncommon among all other crash types or directions. However, they are associated with highest fatality rate than any other crashes, as 33% of fatalities in automobile ... -
