Wind Load Calculations and Modeling

 Part 1 of our Wind Load Series “Wind load” is a calculated value representing the total force on a structure or object cause by pressure from wind moving over it.  In this blog series, we will discuss different methods for wind load calculations, the factors that influence its magnitude, and the effects a high wind load [...]

Thermal Expansion in a Glass and Aluminum Window: Part 2

Figure 1: Simplified model of an aluminum-glass window In last week’s last blog, we explored the causes and effects of thermal expansion in solid materials.  The expansion and contraction of a material based with temperature must be considered in mechanical engineering design projects, since it can impose high and potentially-damaging internal stresses.  We used a simplified aluminum-framed window to demonstrate [...]

Thermal Expansion in a Glass and Aluminum Window: Part 1

Figure 1: Cracked Glass By Andrew Chan [ Content License] Thermal expansion of dissimilar materials is a challenge in designing equipment and structures that are subject to large temperature changes.  This is often called "CTE mismatch." CTE is the acronym for coefficient of thermal expansion.  In this blog, we give the fundamentals of thermal expansion calculations used in thermo-mechanical analysis. [...]

FEA Consulting Part 6: Analyzing Results

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.  [...]

FEA Consulting Part 3: Meshing and Boundary Conditions

Figure 1: Closeup, exploded view of our concrete slab mesh © Glew Engineering Consulting, 2016 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 [...]

FEA Consulting Part 2: CAD Model Preparation

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 [...]

FEA Consulting Part 1: Introduction

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 [...]
