Blunt Force Trauma to the Ribs: Creating Predictive Models
… than any other aspect of the biological profile. Blunt force trauma to the ribs is some of the most common trauma recorded in a medical examiner's setting, however the structural complexity of ribs make it difficult to move beyond descriptive documentation of injuries. The purpose of this study is …

Investigation into the relationship between blunt impacts and bruising
… Although the biology of bruising is known, how a blunt impact initiates bruising and influences its severity is not understood. Furthermore, the standard method of documenting bruising with colour photography is known to have limitations which in turn influence the already subjective analysis of …

The numerical study of 3-dimensional laminar hypersonic blunt-fin interactions
… 7.6 x 106m-1, over several configurations of a blunt-fin attached to a flat plate are carried out. The resulting interference flowfield is reported in this thesis.<br/>The laminar Navier-Stokes code developed by Narvarro-Martinez [47] has been modified to solve any general three-dimensional …

Spatial and temporal deformation pattern of the brain from blunt trauma
… patterns of deformation within the brain during blunt trauma when changing impact parameters. A linear impactor is used to deliver controlled blows to the head surrogate, mimicking real-world blunt injury scenarios. Visual markers within head surrogates are used to motion track deformations and …

Time -Resolved Visualization and Analysis of Compressible Blunt -Base Cylinder Wakes
High-speed flow visualization of these wakes is also performed. Both conventional cross-correlation analysis and cross-correlation analysis conditioned on the coherent structures are performed to measure the convection velocity of the coherent structures. The coherent structures in the developing …

Injury Biomechanics of the Human Eye During Blunt and Blast Loading
… this thesis investigates eye injuries caused by blunt impacts and blast overpressure. This research represents part of an ongoing investigation to accurately quantify and predict eye injuries and injury mechanisms for various loading schemes. It has been shown that blunt trauma can cause severe …

The mechanics of power hacksawing and the cutting action of blunt tools
… indicating that saw blades are basically blunt tools. The cutting action of tools with large cutting edge radii has been investigated and extensive simulation tests have been undertaken. From the observations of the chip formation mechanism and measurements of the relative position of the …

Aerodynamic modeling and assessment of flaps for hypersonic trajectory control of blunt bodies
Independently articulated aerodynamic flaps on a blunt-body entry vehicle may provide a feasible alternative to current state-of-the-art bank-angle steering control while introducing additional benefits during entry, descent, and landing. Flaps provide direct control of the vehicle’s lift and drag …

The sensitivity of composite scarf joints to the height of the blunt tip
… to failure, to changes in the height of the blunt tip, the adherend thickness, and the ratio of the two parameters, defined as the "blunt height ratio". All specimens manufactured for the experimental testing and modeled via finite element analysis were constructed from the same adherend …

MULTIDISCIPLINARY OPTIMIZATION OF NON-SPHERICAL, BLUNT-BODY HEAT SHIELDS FOR A PLANETARY ENTRY VEHICLE
… to find optimal heat shield geometries for blunt-body planetary entry vehicles. In the parametric study, performance trends have been identified by varying geometric parameters that define a range of cross-sections and axial shapes. Cross-sections considered include oblate and prolate …
