Understanding the Effects of Blast Wave on the Intracranial Pressure and Traumatic Brain Injury in Rodents and Humans Using Experimental Shock Tube and Numerical Simulations
ABSTRACT
Blast induced neurotrauma (BINT) has been designated as the “signature injury” to warfighters in the recent military conflicts. In the past decade, conflicts Continue reading
Vibrational Tests of Preloaded Rubber Vibration Isolators: a Cam Controlled Displacement Excitation
Vibrations are very common phenomenon. It influences structures and generates acoustic noise which might be harmful to human beings. The vibration isolator was invented to reduce the effect from vibrations. However, the behavior of Continue reading
Dynamic Analysis of Cracks in Composite Materials
Dynamic analysis of damages in materials is a difficult task and it is currently not known what importance different possible mechanisms carry. It is to a large extent due to Continue reading
Design of a High Altitude Wind Power Generation System
One of the key points to reduce the world dependence on fossil fuels and the emissions of greenhouse gases is the use of renewable energy sources. Recent studies showed that wind energy is a significant source of renewable energy which is Continue reading
Estimating of Work Hardening in Bent Sheet Metal Products at an Early Stage of Virtual Product Development
The thesis has two aims: firstly, to investigate the influence of work hardening due to forming simulation on test simulation. The investigated question was also: Is it worth the effort to include work hardening effect into Continue reading
Simulation of Plume-Spacecraft Interaction
When the plume of a thruster impinges on spacecraft surfaces and instruments, the ow is either in the transitional or the free-molecular regime. The standard method to simulate the transitional regime is Direct Simulation Monte-Carlo, which Continue reading
Simplified Finite Element Bearing Modeling: With NX Nastran
When conducting finite element analysis on the robots the accuracy of the component modelling and definitions of the boundary conditions becomes more important. One such component is the ball bearing which Continue reading
Energy Sector Analysis and Modeling – From Primary to Final Energy
Climate change and energy supply limitation are growing concerns. Solving them requires strong implication from our societies and more and more stakeholders and scientists are therefore Continue reading
Modeling of Direct Contact Condensation With OpenFOAM
Within the course of the project, two thermal phase change models for direct contact condensation were developed with different modeling approaches, namely Continue reading
Vibro-acoustic analysis of a satellite reflector antenna using FEM
The acoustic environment generated during launch is the most demanding structural load case for large, lightweight satellite reflector antennas. The reflector is exposed to Continue reading
