Finite Propagation Speed of Waves in Anisotropic Viscoelastic Media
Finite propagation speed properties in mathematical elastic and viscoelastic models are fundamental in many applications where the data exhibits propagating fronts. We note particularly that this property is observed in biomechanical imaging of tissue, in particular in the supersonic imaging experiment, and also in geophysics and ocean acoustics. With these applications in mind, noting that the...
متن کاملFinite 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...
متن کاملTransient Fluid Flow Modeling in Fractured Aquifer of Sechahoon Iron Mine Using Finite Element Method
Considering the fact that a large volume of iron reserve in the Sechahoon Iron Mine in Yazd Province has located under the water table, it is necessary to conduct a comprehensive study on water flow within the pit and its surroundings. The conceptual model of the aquifer was created using surface and underground geological information compared with water table data of the area of interest. In t...
متن کاملNumerical modeling of transient two-dimensional viscoelastic waves
This paper deals with the numerical modeling of transient mechanical waves in linear viscoelastic solids. Dissipation mechanisms are described using the generalized Zener model. No time convolutions are required thanks to the introduction of memory variables that satisfy local-in-time differential equations. By appropriately choosing the relaxation parameters, it is possible to accurately descr...
