Fig. 1 A street bike shown in CAD mesh. Mechanical Engineering Consulting Group Evaluates 3D CAD Programs Mechanical Engineering Consulting Testing of Creo™, Solidworks™, and Inventor™ Mechanical Engineering Consulting service companies largely use one of three 3D CAD programs: Creo™, Solidworks™, and Inventor™.  At Glew Engineering, we have licensed seats of all three CAD mechanical design packages.  We reviewed the CAD workflow and feature sets of each 3D CAD program using motorcycle frame design as an example.  Also, we showed that some of the specialized commands of each 3D CAD software programs are better suited for specific tasks. Our engineers are experienced with 3D CAD,  stress analysis by Finite Element Analysis (FEA), as well as Computational Fluid Dynamics (CFD) FEA [...]

FEA Consulting Part 6: Analyzing Results

FEA Consulting Part 5: Generating Results

As a [...]

FEA Consulting Part 4: Simulation and Analysis

Figure 1: Mesh, loads and constraints, ready for analysis © Glew Engineering Consulting, inc. 2016 Welcome again to our series on finite element analysis (FEA).  In the last blogs, I covered steps on setting up a computer-aided design (CAD) model and how to set up the mesh and boundary conditions, the most crucial steps in FEA simulation.  In this blog, I’ll look at the actual simulation and analysis, which can be the most time-consuming stage in the process. As a reminder, for an example I’ve been using a recent project we worked on involving punching shear in reinforced concrete.  We were examining the effectiveness of reinforcing a column-supported concrete slab against the possibility of that column punching through the concrete. Types of [...]

FEA Consulting Part 3: Meshing and Boundary Conditions

2018-03-27T15:27:13+00:00

We'll continue on now with our blog series on finite element analysis (FEA).  After discussing how to best set up a computer-aided design (CAD) model for FEA simulation, in this blog I'll cover the next step: meshing the model and applying boundary conditions.  "Meshing" is the process by which the CAD model is separated into discrete finite elements; it can be done in the same program that runs the FEA numerical simulation later, or it might be performed in a standalone program, depending on your software.  Boundary conditions are the loads (forces, movements, impacts, etc) and constraints that interact to actually cause deformation and stress in each element, and in turn the model as a whole. Mesh Generation The mesh essentially [...]

FEA Consulting Part 2: CAD Model Preparation

2017-05-02T16:56:01+00:00

Figure 1: Reinforced concrete mesh © Glew Engineering Consulting Welcome back to our blog series on FEA.  In the last blog entry, we introduced some of the fundamental concepts in finite element analysis (FEA).  This entry in the blog series focuses on the initial steps in preparing a computer-aided design (CAD) model ready for use in an FEA program.  Since FEA programs are very sensitive to the data they have to work with, it's important that the CAD models being analyzed are compatible with the analysis methods the FEA program uses. In order to illustrate my points throughout the blog series, I will introduce a recent FEA consulting project that we completed. Modeling Punching Shear in a Concrete Slab We were recently approached by an academic, who was examining [...]

FEA Consulting Part 1: Introduction

2018-03-23T10:52:25+00:00

Figure 1: FEA mesh and shear stress results for a reinforced concrete slab © Glew Engineering Consulting, 2016 Finite Element Analysis Consulting (FEA) In this series of blogs on FEA, we will first cover some basic elements common to many FEA projects, and then in subsequent blogs in this series, illustrate those methods through examples. One of the services that Glew Engineering Consulting provides is finite element analysis consulting (FEA).  FEA consulting has been a great boon to the engineering profession, allowing mechanical engineers and civil engineers to accurately model the stress and strain behavior of complicated parts and assemblies prior to building physical prototypes.  FEA programs are capable of predicting the effects of loads and impacts, variations in temperature, changes in pressure, and [...]
