Italian Masters: Leonardo da Vinci – Artist, Engineer, Scientist

2018-02-20T13:14:29-08:00

Figure 1: Leonardo da Vinci, by Francesco Melzi Over the course of this blog series, I have written about a number of Italian Masters of science and engineering, from astronomers like Galileo and Cassini to physicists like Torricelli and Venturi.  I’ve saved the best for last, however: Leonardo da Vinci.  He is the quintessential renaissance man who fits both our running definition of “Italian Master” as well as being included in the standard list of Masters with Rafael, Donatello and Michelangelo  Leonardo’s incredibly broad array of talents and interests have long been the subjects of movies, books, TV shows, and, of late, [...]

Italian Masters: Volta Jump-Starts Electrical Engineering

2018-02-21T10:28:40-08:00

Italian Masters: Volta Jump-Starts Electrical EngineeringFigure 1: Girolamo Cardano (1501-1576) Welcome back to our series on Italian Masters of math and science.  Last week I wrote about Galileo’s extensive accomplishments both in the field of astronomy and beyond.  This week, I’ll take a look at another renaissance polymath who dabbled in astronomy, along with his work in mathematics, medicine, biology, chemistry, philosophy, and gambling (yes, seriously): Girolamo Cardano.  Cardano is a less well-known figure than Galileo or some of the other scientists I’ve written about who have famous equations or units of measurement named after them, like Volta or Torricelli.  He [...]

Italian Masters: Galileo’s Stellar Science and Engineering

2018-02-21T10:55:17-08:00

Portrait of Galileo Galilei Justus Sustermans [Public domain], via Wikimedia Commons I’d like to return to our previous series on the Italian Masters, focused not on the usual masters or painting and sculpture but on the masters or science, mathematics, and engineering.  So far in the series I’ve written about the accomplishments of Volta, Cassini, Venturi and Torricelli.  Today, I’d like to look at one of the greats: Galileo Galilei.  Galileo is most famous today for standing up for heliocentrism against the Catholic Church and spending the last years of his life under house arrest as [...]

FEA Consulting Part 3: Meshing and Boundary Conditions

2018-03-27T15:27:13-07:00

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 [...]

Italian Masters: Venturi and the Venturi Effect

2017-05-03T14:48:59-07:00

Figure 1: Giovanni Battista Venturi [i] Glew's News is doing a short series highlighting the lives and accomplishments of the Italian Masters of science, engineering, and mathematics.  In the last blog, I wrote about Evangelista Torricelli, a mathematician and physicist from the 17th century.  In this blog, I'm focusing on Giovanni Venturi (Figure 1), an accomplished physicist, hydrodynamicist and engineer. Giovanni Battista Venturi (1746-1822) Giovanni Venturi was born to a wealthy family in Reggio, Italy in 1746.  A talented young student, by the age of 23 the local seminary had already ordained him as a priest and professor.  [...]

FEA Consulting Part 2: CAD Model Preparation

2017-05-02T16:56:01-07:00

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 Part 1: Introduction

2018-03-23T10:52:25-07:00

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 [...]
