The present study focuses on the design and analysis of a single-engine, propeller-driven general aviation airplane. Initial weight estimation based on the initial sketch and the design mission profile is conducted. The estimated weight and other design parameters are used to define the external geometry of the fuselage, wing and tail. Conic lofting is utilized to render a layout of the design ...

Spondylolysis (SL) is a defect of the spinal vertebra, and is typically caused by stress fracture of the pars interarticularis bone of the vertebral arch. It is especially common in adolescents who over train in sporting activities. Spina bifida occulta (SBO) is a malformation of the spine where the protruding vertebral bodies are not fully formed. In this study we demonstrate the predisposition ...

The present work aims to develop a blood pressure sensor using MEMS/NEMS technology. A normal blood pressure detector is used externally, but this work mainly aims for designing an implantable nanotube based sensor for continuous monitoring of blood pressure. The use of COMSOL Multiphysics 4.1 acts as a good platform to develop a nano tube based sensor design by using the MEMS module. The ...

Structural analysis is performed to check the durability of Engine mounts for a given load and support conditions. The engine mount bracket is subjected to loads primarily due to weight of the powertrain and the unbalanced torque. In this analysis, the component is optimized such that stresses generated do not exceed the endurance strength of the material. In this paper, structural mechanics ...

The Large Hadron Collider at CERN has begun operations at 7 TeV center of mass energy. CERN plans to run at this energy until the end of 2012 with the goal of providing an integrated luminosity of a few fb?¹ to the CMS and ATLAS experiments. The LHC will then shut down for 1.5 to 2 years to make the revisions necessary to run at ~14 TeV. Operation resumes in 2014. In 2017/18, there will be ...

Bridge piers and abutments makeup the bridge substructure and transmit loads from the superstructure to the bridge foundation material (Figure 1). The bridge abutment serves three purposes: to provide vertical support to the bridge superstructure where the bridge ends, to connect the bridge with the approach roadway, and to retain roadway base materials. There are several types of abutment ...

Our goal is to reproduce the key features of carangiform swimming by running 2D simulations which fully exploit the Fluid-Structure Interaction interface of COMSOL Multiphysics software. Fish swimming is an important area of research, with relevant developments on biomechanics, robotics and mathematical modeling. Usually, in fish swimming simulations, the motion of the fish is assigned, and much ...

In this paper, a model for numerically obtaining lamb wave modes and dispersion curves in plates is presented. It is shown that COMSOL Multiphysics can be employed to simulate the behavior of guided waves in dispersive plates, which is useful for NDE applications. A two dimensional steel plate (4x0.1 meters) is excited with a space-time impact point source. To model the point source, we use ...

Introduction: Glass relaxation occurs in a range of temperature during transition from equilibrium to super-cooled liquid. Viscoelastic material model can be applied to simulate glass behavior during the glass transition regime and to predict the glass deformation and stress evolution. Viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when ...

Capacitor is mainly defined as two conducting plates that can hold the opposite charges on it. These plates can be used either as a sensor or an actuator. If the relative distance between the two conductors changes as result of given input, then capacitance values will change. This results in basic of capacitive or electrostatic sensing configuration. On the other hand, if a voltage or the ...
