Evaluation of the occupant response and structural damage according to the newly proposed pole test under Federal Motor Vehicle Safety Standard side impact regulation

Siruvole, Sandeep Kumar (2007-05)

Every year around the world various types of automobile accidents occur, out of which side impact vehicular collisions are the most severe. Of these, side crashes into fixed narrow objects like trees, poles account for ...
Examination of lateral deviation of a projectile subjected to internal gyroscopic forces

Umstead, Christopher M. (Wichita State University, 2009-12)

The need for lateral travel can arise in a simple projectile either due to the target moving or to a transverse external force that moves the projectile. By the use of internal moving parts, a force in the lateral direction ...
Experimental and computational aerodynamic analysis of ice fragments shed from aircraft surfaces

Jacob, Joel (2006-12)

Icing can pose problems due to both accretions on aircraft aerodynamic surfaces as well as through shedding of large ice particles from aircraft surfaces. The shed ice causes damage by impacting downstream aerodynamic ...
Experimental and numerical study of distortion in flat, L-shaped, and U-shaped carbon fiber-epoxy composite parts

Roozbehjavan, Pooneh (Wichita State University, 2012-07)

In this work, the effect of different parameters, including stacking sequence, part thickness, and tooling material, on distortion of flat panels was investigated. A Romer arm equipped with a laser scanner was used to ...
Experimental determination of strain rate and flow stress in the primary shear zone while machining AISI 4340 and Ti-6AL-4V

Srinivasan, Kiran (Wichita State University, 2010-08)

Metal cutting subjects the material being cut to high strain rates (103 -106/s) and strains>100% within the primary shear zone (PSZ). This thesis is aimed at quantitative measurement of the strain, strain rate and flow ...
Experimental determination of velocity and strain rate fields in metal cutting of OFHC copper

Mahadevan, Dinesh (Wichita State University, 2007-12)

Metal cutting subjects the material being cut to strains greater than 100% at high strain rates between 103/s and 106/s and may be a good test for mechanical properties in this strain rate regime. This thesis presents an ...
Experimental evaluation of 802.11e quality of service in a large-scale network

Chung, Pui See (Wichita State University, 2010-08)

IEEE 802.11e is a fairly recent amendment to the IEEE 802.11 WLAN standard that supports quality of service (QoS) (or service differentiation) based on medium-access control (MAC) and contention-based channel access. While ...
Experimental investigation and analysis for bearing strength behavior of composite laminates

Yeole, Amit (2007-05)

An investigation of joint strength in bolted connections for Carbon unitape material [0/45/-45/90]3s is presented. The simple case of bearing double shear joint is considered. In the first stage the objective of work was ...
Experimental investigation of fiber sizing-test fluid interaction for in-plane permeability measurements of continuous fibers

Dukkipati, Ravi Kiran (Wichita State University, 2007-12)

Many manufacturers are using liquid composite molding (LCM) to manufacture composites because of its simplicity and cost effectiveness. This generic process includes techniques such as vacuum assisted resin transfer molding ...
Experimental investigation of potting compound strength enhancement through the use of carbon nanomaterials

Baalman, Jonathan (Wichita State University, 2008-05)

Carbon nanomaterials have recently been discovered which possess many unique physical properties. Multiple attempts have been made to integrate these materials into new technologies, including carbon nanocomposites with ...
