Finite element and analytical models for load transfer calculations for structures utilizing metal and composites with large CTE differences
(2007-05)Large composite structures have been increasingly used in the aviation industry. In order to achieve higher fuel efficiency, the use of light-weight, high-strength composite materials, such as carbon/epoxy, needs to be ... -
Finite element application for strength analysis of scarf-patch-repaired composite laminates
(2006-12)The composite scarf joint configuration was utilized to simulate scarf-patch-repaired composite panels. An adhesive bonded scarf (tapered) joint was selected due to less peeling and shear stress over the bondline than with ... -
Finite element based modeling of magnetorheological dampers
(2006-12)For an efficient damper design, a design engineer always faces the challenge of providing the largest forces in the most compact and efficient envelope. It is important to identify the nature of the force required at the ... -
A finite element model to study the torsional fracture strength of a composite tibia
(Wichita State University, 2009-12)Screws are common orthopaedic hardware used to secure a fractured bone. After the bone has healed, the screws may be removed, and the vacant screw holes introduce a potential site for re-fracture, which is a known ... -
Finite element modeling and analysis of cold ring rolling
(Wichita State University, 2009-05)Cold ring rolling is a complex metal forming process and generally not well understood. In many instances, considerable experience and experimentation is required to develop the process. During the process, plastic deformation ... -
Finite element modeling and side impact study of a low-floor mass transit bus
(2006-12)Mass transportation systems, specifically bus systems, are a key element of the national transportation network. Buses are one of the safest forms of transportation; nonetheless, bus crashes resulting in occupant injuries ... -
Finite element modeling of a medium load transfer specimen under high speed loading
(Wichita State University, 2014-12)A three dimensional finite element model for a single-shear medium load transfer aluminum rivet joint specimen is used to study the installation parameters such as rivet/hole clearance, riveting squeeze force and material ... -
Finite element modeling of energy absorption characteristic of hybrid structure - composite wrapped on a square metal tube
(2006-05)The study of axial crush behavior of metal and composite tube has become a basis for the design of crashworthy structure in automotive and aircraft applications. Unlike metals, polymer composite material displays little ... -
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
