H.; BATTELLE COLUMBUS DIV OH Abstract: A finite element analysis of stationary and propagating cracks in the presence of inertia forces is presented. An extension of the J-integral approach is employed. To model a propagating crack, a conceptually simple yet effective technique has been developed. The new crack propagation scheme eliminates the difficulties associated with the use of moving singular elements.

View, CA ABSTRACT Introduction The Role of FEA Finite element analysis is emerging as one of the most important tools available to material sensitive product developers. [1] The technique has unique capabilities and can be a very cost-effective tool if properly used. There are a number of very good reasons why one might want to do simulations of the mechanical behavior of medical devices or components. For example, ascertaining the functionality of the devices is certainly a first requirement, however, there are many other potential reasons related to such important issues as the effort required for deployment of the part, stresses induced in parts, durability, etc. Each of these is also commonly associated with the execution of such simulations. Simulation and modeling allows the prediction of behavior before any physical building occurs. This allows the designer to examine ny number of "what if" scenarios in optimizing the design. Simulation can lso provide detailed insight into the mechanical behavior of the design, which may not be discoverable through normal testing and experimentation. Simulation cannot be done without physical properties and some simplifying assumptions are inevitably made. Thus simulation is a complement and amplifier to testing, rather than a substitute.

BBC Forensic Engineering - Modern Methods - Finite Element Analysis the calculations were numerical and elements were often small in relation to the size of components or structures, the use of the finite element method was http://www.open2.net/forensic_engineering/methods/advances/advances_05.htm

This method depends on the dividing up of a body into discrete elements, which may be triangles, squares or other defined shapes, and analysing the response of the body as a whole as the sum of what the response is of each element of the body. Each element is characterised by the value of a quantity (stress, displacement) at the nodes (corners) of the element and values at points in between were estimated by interpolation. The method was developed in the 1950s for problems in structural engineering, especially in the aeronautical industry. The first usage of the term "finite element" came in 1960 and the generalisation of the method to solve problems in fields other than structural engineering, such as heat transfer, came in the late 1960s. Since the calculations were numerical and elements were often small in relation to the size of components or structures, the use of the finite element method was somewhat restricted until cheap powerful computing facilities (hardware and software) became available. Initially, problems tackled by this method were one-dimensional but the developments of the method, especially with increased computing power available, has been extended to two and three dimensions.

These are exact SIF's and are independent of R/T, d/D, or t/T ratios, as in the standard B31 SIF tables. FE/PIPE also produces an SIF report which provides comparison with B31.1, B31.3, WRC 330, WRC 107, and WRC 297 values, using the same basis throughout. By using the SIF's generated by finite element analysis, accuracy of "beam-type" analysis such as pipe flexibility calculations, can be greatly improved. Nozzle flexibilities calculated by FE/PIPE can similarly be used to increase accuracy in "beam-type" calculations. An estimation of load reduction due to the use of the finite element calculated flexibilities, is also provided. Stress calculation can be made in FE/PIPE according to WRC107 and WRC297, and a comparison made with the finite element calculated stresses. This allows the user to be able to see when WRC values are actually valid. This is useful since the WRC guidelines were originally based on a limited range of test data.

References Background Few finite element models (FEM) have been developed to describe the electric field, specific absorption rate (SAR), and the temperature distribution surrounding hepatic radiofrequency ablation probes. To date, a coupled finite element model that accounts for the temperature-dependent electrical conductivity changes has not been developed for ablation type devices. While it is widely acknowledged that accounting for temperature dependent phenomena may affect the outcome of these models, the effect has not been assessed. Methods The results of four finite element models are compared: constant electrical conductivity without tissue perfusion, temperature-dependent conductivity without tissue perfusion, constant electrical conductivity with tissue perfusion, and temperature-dependent conductivity with tissue perfusion.

Dictionaries: General Computing Medical Legal Encyclopedia Finite element analysis Word: Word Starts with Ends with Definition Finite element analysis (FEA) is the application of the finite element method In numerical analysis, the finite element method is used for solving partial differential equations (PDE) approximately. Solutions are approximated by either eliminating the differential equation completely (steady state problems), or rendering the PDE into an equivalent ordinary differential equation, which is then solved using standard techniques such as finite differences, etc. Use of the finite element method in engineering for the analysis of physical systems is commonly known as finite element analysis.
