Finite Element Modeling of an Ultrasonic Transducer

Ultrasonic transducers are integrated into the minimally invasive needles and catheters for medical diagnostic. There is a need for a model that can predict the behavior of the ultrasonic transducer. Many designers employ one dimensional analytic models, however due to certain limitations these models are not adequate to understand the entire performance of an ultrasonic transducer. Nowadays, f...

Analysis of Strain Inhomogeneity in Vortex Extrusion using Finite Element Method and Response Surface Methodology

The effect of geometrical parameters involved in vortex extrusion (VE) die design, on AA1050 aluminium alloy processed by VE were investigated using finite element analysis (FEA) and response surface methodology (RSM). For this, VE die length (L), reduction in area (RA), twist angle , and position of control points in Beziers' formulation (C1) were considered as input parameters and strain inho...

Finite Element Modeling of a Capacitive Micromachined Ultrasonic Transducer

Transducers based on piezoelectric crystals dominate the biomedical ultrasonic imaging field. However, fabrication difficulties for piezoelectric transducers limit their usage for complex imaging modalities such as 2D imaging, high frequency imaging, and forward looking intravascular imaging. Capacitive micromachined ultrasonic transducers (CMUTs) have been proposed to overcome these limitation...

Finite Element Analysis of a Flexure Based Ultrasonic motor

The ineluctable change to micro and subsequently nano has engendered the need for precision control and actuation. With Piezoelectric technology at the heart, a new type of motor is improving small-scale motion systems in a big way. In the following study a novel design of a travelling-wave-type motor based on flexural excitations (d-15 effect) is analyzed using finite element method. The objec...

Finite Element Simulation of Hydrostatic Extrusion Process to Produce Thin Bimetallic Parts

The hydrostatic extrusion is a new method of extrusion process. The most important advantage of this method is reduction of friction and close tolerance for the coating thickness. In this study, the hydrostatic extrusion simulation of bimetallic wires has performed using of finite element method. In the following the advantages of hydrostatic extrusion compared to the direct extrusion are prese...
