Modular orthopaedic devices are a feature of total joint replacements today. These modular orthopaedic devices allowing surgeons to choose from a variety of available implant sizes, designs & material options for the procedure required and the patient specific requirements. However, even though this allows for greater scope of implant construction, if the various components of the modular design ...

The use of thermoplastic materials is increasing and it is becoming more important during the design process to accurately represent the non-linear material response in relevant loading conditions. The COMSOL Multiphysics® software supports advanced modeling capabilities for large deformation analyses, including contact and multiphysics couplings. It is now also possible to use advanced non ...

This paper describes the use of structural mechanics capabilities within COMSOL to explore new cooling catheter designs. Cooling catheters may be used to save ischemic tissue resulting from strokes or heart attacks. Typical guide catheters use metallic braiding to ensure torsional strength. Braiding, however, displaces space for flows and limits design options. To explore alternatives to ...

Reduction of the engine vibration and the dynamic forces transmitting from engine to the automotive body structure has always been an important part of automotive research. Automobile engineers face the task of creating a mechanism to absorb these vibrations and provide a smooth ride. The usage of Motor Mounts is the best solution for dampening the effects of vibrations and oscillations. This ...

Wind turbines are the conventional type of energy source. The main focus of this work is the analysis and fabrication of cost effective VAWT. Cost of the turbine is reduced by low cost material and minimizing its total weight. There are two main types of the wind turbines i.e. Horizontal Axis Wind Turbine and Vertical Axis Wind Turbine. Savonious VAWT is preferable for energy generation, because ...

To reduce friction in lubricated tribological contacts, the surfaces of the contacting bodies can be microstructured to improve lubricating conditions. For lower loaded contacts this approach has already reached industrial applications, e.g. the piston-liner contact. For higher loaded contacts the effects are currently in basic research. Elastic deformation in the contact area plays an important ...

Metal reed valves are used for flow rectification in electrohydraulic pumps driven by smart materials at high frequencies but it is difficult to predict their behavior when the surrounding fluid has considerable inertia and viscosity. Simulation of this phenomenon involves modeling the fluid-structure-interaction between the bending of the reed and the flow past the valve. In this model, we use ...

Thermal elastohydrodynamic lubricated (TEHL) contacts occur very frequently in drive technology and thus in gear drives. In this presentation, the implementation of a finite element based TEHL simulation approach for gear contacts in COMSOL Multiphysics® software is shown. The physically based simulation approach used is different to most of the existing TEHL simulations and is required to ...

The complex behavior of biological prosthetic heart valves was simulated. A multiphysics computational approach was adopted using different modules of COMSOL Multiphysics: the LiveLink(TM) interface was used to exchange the valve geometry with CAD, Structural Mechanics Module to set loads, boundary conditions and implement anisotropic hyper-elastic constitutive laws for leaflet tissue, PDE to ...
