Finite element modeling of low floor mass transit bus and analysis of frontal impact scenarios
(2006-12)There is no international regulation for the frontal collision of the buses, protecting their occupants and partners in traffic. There are some regulation such as ECE R-80 which deals with strength of seat structure of the ... -
Finite element modeling of single shear fastener joint specimens: A comparison of simplified joint modeling techniques
(Wichita State University, 2014-12)Simplified finite element joint models were compared to a detailed three-dimensional model at coupon level to study their performance. Simplification of bolted joints is warranted by the element size limitation present ... -
Finite element modeling of single shear fastener joint specimens: a study of clamp-up, friction and plasticity effects
(Wichita State University, 2011-12)A three dimensional solid finite element model was assembled to investigate the influence of parameters such as friction coefficient, fastener preload and material plasticity on the structural response of Hi-Lok bolted ... -
Finite element simulation of 3D drilling in unidirectional CFRP composite
(2006-05)Drilling is probably the most important conventional mechanical process and it is the most widely used machining operations. Prediction of cutting forces for any set of cutting parameters is essential in optimal design and ... -
Finite element simulations of ballistic impact on metal and composite plates
(Wichita State University, 2007-12)Response of a material impacted by projectiles especially bullets, or blast fragments, is extremely important in determining the range of impact it can sustain. As explicit finite element codes improve and advances material ... -
Finite element study of energy absorption in corrugated beams
(2005-12)This work is focused on the finite element study of the energy absorbing behavior of aluminum (corrugated webs). The aim is to study the mechanism of energy absorption in specific metallic structures by understanding these ... -
Fire retardancy of nanocomposites incorporated with graphene and nanoclay inclusions
(Wichita State University. Graduate School, 2013-05-08)The applications of polymeric materials in many industries show the great importance of these materials. Due to their molecular structure and chemical composition, polymeric materials are highly flammable. This study is ... -
Fire retardancy of polymeric materials incorporated with nanoscale inclusions
(American Society of Mechanical Engineers, 2014)Polymeric materials have a wide variety of applications in many manufacturing industries. However, because of the molecular structures and chemical compositions of polymeric materials, they have considerably low resistances ... -
Fire retardancy, thermal stability and mechanical properties of polymeric based nanocomposites
(Wichita State University, 2013-12)Polymeric materials have a wide variety of applications in many manufacturing industries. However, because of the molecular structures and chemical compositions of polymeric materials, they have considerably low resistances ... -
A first best toll pricing framework for variable demand traffic assignment problems
(Elsevier, 2005)In this paper, we present a toll pricing framework for a general variable demand traffic assignment problem with side constraints, where the demand between an origin destination pair is a function of the least total travel ... -
The first stage in two-stage template matching
(IEEE, 1985-11)This paper formulates the problem encountered in the first stage of two-stage, binary template matching as a set of hypotheses to be tested, including a hypothesis of "no object." Two new statistics R and G are proposed, ... -
Five heads are better than one: an interdisciplinary graduate course on Smart Grids: lessons, challenges, and opportunities
(IEEE-INST Electrical Electronics Engineers Inc, 2013-01)According to the U.S. Department of Energy (DOE ), “Smart grid generally refers to a class of technology people are using to bring utility electricity delivery into the 21st century, using computer-based remote control and ... -
Flexible autonomous robotic task scheduling using advanced RISC machines
(Wichita State University, 2008-08)This research presents two methods for a group of Garcia robots to collaboratively decide which task to attend to, and to move to their respective locations. One method allows for a needed flexibility and dynamic analysis ... -
