Sex-Based Differences in Calcaneal Injury Tolerances Under High-Rate Loading
… mounted in a custom fixture and exposed once to high-rate axial loading characterized by a constant acceleration and 25.4mm intrusion, achieving an average speed of 4.7m/s (σ = 0.3m/s) in 10ms. Input acceleration was measured by an Endevco 7264c accelerometer and a Denton 2513 six-axis load cell …

Bond between reinforcing bars and concrete under impact loading
… reinforcing bars and concrete under impact loading was studied for plain, polypropylene fibre reinforced, and steel fibre reinforced concretes. The experimental program included setting up an impact test system, in which an impact load with considerable energy could be generated, and in …

Mechanics of Notched Izod impact testing of polycarbonate
… measuring energy absorbed prior to failure under high triaxiality and high rate loading conditions. Much research has been done using Izod testing to compare the fracture energies of blends of Polycarbonate and rubbery materials; however the specific yielding and fracture mechanisms associated …

The Biomechanical Response of the Eye, Face, and Orbit to Primary Blast Overpressure
… on how the body responds to the relatively low loading rates associated with blunt trauma, little is known regarding the response of the body to the higher loading rates associated with blast trauma. While soldiers are surviving once-lethal blast events due to enhanced protective equipment, …

Attributes of Astrocyte Response to Mechano-Stimulation by High-Rate Overpressure
… incidence of blast neurotrauma is particularly high amongst military combat personnel and can be debilitating and endure clinically for years after injury is sustained. Mechanically, blast represents a unique and complex loading paradigm associated with compressive shock waves that propagate out …

Characterisation of Glass Fibre Polypropylene and GFPP based Fibre Metal Laminates at high strain rates
… increasing use in structures subjected to high rate loading such as blast or impact. Proper design of such structures requires thorough characterisation of the material behaviour over a range of loading rates from quasi-static to impact. This thesis investigated the quasi-static and impact …

Einfluss von Temperatur und Beanspruchungsrate auf das Festigkeits-, Verformungs- und Zähigkeitsverhalten des Stahls G42CrMo4 mit unterschiedlicher Einschlusscharakteristik
… auf das temperatur- und beanspruchungsratenabhängige Festigkeits-, Verformungs- und Zähigkeitsverhalten des Stahls G42CrMo4 wird erforscht. Die im Rahmen des SFB 920 entwickelten Filter mit funktionalisierter Oberfläche dienten der Reinigung einer vorher bewusst verunreinigten …

A new energy absorber for earthquake resistant buildings
… The device as well as being capable to absorb high amount of energy, possess all the necessary properties of a structural member. Most energy absorbing devices have not the necessary conditions to be used as a structural members. Their problems have been demonstrated in chapter 1 and chapter 3 …
