The Electromagnetic Aircraft Launch System (EMALS) offers significant benefits to the aircraft, ship, personnel, and operational capabilities. EMALS has such advantages as high thrust, good controllability, reusable, etc., as a launching motor, a double-side plate Permanent Magnet Linear Synchronous Motor (PMLSM) can provide high instantaneous thrust. This paper presents the design and analysis...

Detailed finite element modeling of the human body offers a potential major enhancement to the prediction of injury risk during vehicle impacts. Currently, vehicle crash safety countermeasure development is based on a combination of testing with established anthropomorphic test devices (i.e., ATD or dummy) and a mixture of multi­ body (dummy) and finite element (vehicle) modeling. If a relative...

Virtual prototyping has gained major importance in the development cycle of new products. The finite element method has mostly replaced real experiments performed on expensive solid models. To accomplish modeling tasks on the virtual models, a lot of software has been developed over the past years. However, most of such software packages do not focus on intuitive handling of the discretized com...

Electric circuit analysis determines the voltage and current distribution in an electric circuit due to applied source voltages or currents. In a static (DC) electric circuit analysis, the voltage and current distribution in an electric circuit is determined that is subjected to applied DC source voltages or currents. In a harmonic (AC) electric circuit analysis, the voltage and current distrib...

Origami has become a source of inspiration in engineering for structural design and the creation of mechanical metamaterials. In the often used analytic geometric and energy methods, it is difficult to incorporate deformation of the faces in non-rigid origami. However, deformation of the faces can play a significant role in their mechanical behaviour. This thesis aims to investigate and improve...

The porous microstructures of metallic foams cause microscopic stress and strain localization under deformation which reduces the damage tolerance and therefore limits application of the materials. In this paper, the deformation of a relatively low porosity porous titanium is examined using two-dimensional (2D) plane strain and three-dimensional (3D) finite element models to identify the accura...

Discharge tubes in hermetically sealed refrigeration compressors are often a source of fatigue failure which is not serviceable and necessitates the replacement of the compressor. The finite element method can be used to model the discharge tube to help prevent such failures and to reduce costs by optimizing the tube. This investigation considers techniques for modeling discharge tubes with fin...

The theory of contact mechanics deals with stresses and deformations which arise when the surfaces of two solid bodies are brought into contact. In elastic deformation contact occurs over a finite area. A regular method for determining the dimensions of this area is Hertz Contact Model. Appearance of atomic force microscope results in introduction of Contact ...
