This monograph describes various methods for solving deformation problems of particulate solids, taking the reader from analytical to computational methods. The book is the first to present the topic of linear elasticity in mathematical terms that will be familiar to anyone with a grounding in fluid mechanics. It incorporates the latest advances in computational algorithms for elliptic partial differential equations, and provides the groundwork for simulations on high performance parallel computers. Numerous exercises complement the theoretical discussions, and a related set of self-documented programs is available to readers with Internet access. The work will be of interest to advanced students and practicing researchers in mechanical engineering, chemical engineering, applied physics, computational methods, and developers of numerical modeling software.

Bending Radius

The bending performance of lead frame materials is a very important in improving the quality of lead frame alloys and meeting the needs of high performance integrated circuit. The sringback amount of curvature variation of CuFeP , CuCrZrMg , CuNiSi and CuCrSnZn alloy are researched by numerical simulation. Bending model is built by 3D modeling software, and the necessary post-processing is carried out. The bending springback amount △K of the four kinds of copper alloy materials are calculated out. The results show that the sringback amount of curvature variation of four copper alloys at the same condition from large to small in turn is CuCrZrMg, CuNiSi, CuFeP, CuCrSnZn. Smaller the minimum relatively bending radius of copper alloy used in lead frame, less the springback amount and better the forming performance.

The article deals with the application of cloud computing to solve the problems of construction and analysis of engineering system acceptability regions (AR). It is claimed that the cloud plat-form is the most appropriate architecture for consolidating high-performance computing re-sources, modeling software and data warehouses in multi-user mode. The main components of the cloud environment for (AR) construction and analysis within the framework of the SaaS and DaaS cloud service models are discussed.

And Performance

We theoretically investigate a 25 GHz multichannel filter based on ring cavity birefringent optical interleaver for dense wavelength division multiplexing (DWDM) transmission systems. The simulation tool used in this work is the Advanced System Analysis Program (ASAP) optical modeling software. We improve the dispersion performance by employingλ/6 andλ/4 wave plates as birefringent compensators for interleavers. The new structure exhibits a high performance with nearly zero ripple, a channel isolation greater than 102 dB, and a passband utilization of 86% within the C-band. The research results illustrate that our modified scheme can improve the dispersion of more than 76.6% in comparison with the previous studies of optical interleaver with birefringent crystal and ring cavity structures.

This paper describes a web-enabled tool capable of generating high quality videos and images from multibody dynamics simulation results. This tool, called Chrono::Render, uses the Blender modeling software as the front end with Pixars RenderMan used to create high quality images. Blender is a free and open source tool used to create and visualize 3D content and provides a robust plugin framework which Chrono::Render leverages. To produce the final image, the Blender front end passes data to a RenderMan compliant rendering engine. Along with Pixars PhotoRealistic RenderMan (PRMan), several open source options such as Aqsis, JrMan, or Pixie can be used. Preprocessing is performed on the client side, where the front end generates a work order for the RenderMan compliant rendering engine to process. This work order, which contains several scripts that define the visualization parameters, along with the pre-processed simulation data and other user-defined geometry assets is uploaded to a remote server hosted by the Simulation Based Engineering Lab. This server contains more than a thousand CPU cores used for high performance computing applications, which can be used to render many frames of an animation in parallel. Chrono::Render is free and open source software released under a BSD3 license.

3D Scene

Rendering an image from a 3D scene requires a large amount of computation and designers need to use high-performance computer systems to keep the rendering time acceptable. They usually rent computing power directly from cloud service providers (e.g. AWS and Azure). However, integrating them within the standard workflow of modeling softwares can become a complex task. This project uses an extension of OpenMP 4.X 1-2 to eliminate any major interactions with the end-user, minimizing the complexity of cloud integration and optimizing the workflow. It applies such approach to a ray-tracing application, a simplified version of the engines used by professional 3D modeling software (e.g. Blender 3). It automatically offloads the rendering process from the user computer to computer cluster within the Microsoft Azure cloud, brings the resulting images back after the computation ends and displays them directly on the screen of the user computer, thus providing a transparent programming model and good speed-ups over local execution.

Electron Energy Loss

A double focusing magnetic spectrometer has been constructed for use with a field emission electron gun scanning microscope in order to study the electron energy loss mechanism in thin specimens. It is of the uniform field sector type with curved pole pieces. The shape of the pole pieces is determined by requiring that all particles be focused to a point at the image slit (point 1). The resultant shape gives perfect focusing in the median plane (Fig. 1) and first order focusing in the vertical plane (Fig. 2).
