Abstract: In this paper, the forming process of a central hub by radial-forward extrusion is analyzed by using the finite element software, ABAQUS. Radial-forward extrusion is used to produce hollow parts that generally feature a central hub with radial protrusions. Effective design factors such as mandrel diameter, die corner radius, die fillet radius, mandrel corner radius, tube wall thick...

Micro-electro-mechanical systems (MEMs) are Combination of electrical and mechanical components in Micron dimensions. In recent years, holding, actuating methods and handling of MEMs components such as microgripper, microsensors and etc. have been deeply studied. Microgrippers for handling, positioning and assembling of micro components are very useful so that for clamping need actuation create...

Purpose The purpose of this paper is to present the freely available finite element simulation software Pyrit . Design/methodology/approach In a first step, design principles and objective project are defined. Then, software’s structure established: organized in packages for which an overview given. based on typical steps workflow, i.e., problem definition, problem-solving post-processing. Stat...

Abstract Many works in capacitive deionization (CDI) use finite-element (FEM) simulations to investigate process behavior. Here, we present ELC, comprehensive software that integrates these methods with COMSOL Multiphysics. It can save significant time for common research questions CDI operations and is well-suited new complex upscaled device designs. The ELC has already been used the ...

The hp -adaptive finite element method—where one independently chooses the mesh size ( h ) and polynomial degree p to be used on each cell—has long been known have better theoretical convergence properties than either - or methods alone. However, it is not widely used, owing at least in part difficulty of underlying algorithms lack usable implementations. This particularly true when with contin...
