Good News for Materials Scientists - Semiconductor Record Spending Fab spending reports show unprecedented high semiconductor equipment sales are being driven by a handful of well-known companies, and also by several new Chinese companies entering the semiconductor marketplace. An increase in overall fab spending (greenfield construction and equipment together) of 54 percent year-over-year (YoY) in China is expected. Total spending in China rose from $3.5 billion in 2016, to $5.4 billion in 2017, and then is anticipated to be $8.6 billion in 2018, another 60 percent year-over-year (YoY). The demand for Materials Scientists to develop manufacturing processes and engineers to install and maintain the equipment will be huge as well . Fab Spending is Beyond Silicon Valley China-based companies [...]

A Licensed Mechanical Engineer at Glew Engineering Consulting was asked by a company in Southern California to provide a Professional Engineer (P.E.) review of body modifications that they made to a theme park owned 1983 Sport Utility Vehicle (SUV) that they had converted to an electric vehicle. Figure 1. A Mechanical Engineer Analyzed the Front of Custom Sport Utility Vehicle Licensed Mechanical Engineer Reviews a Modified Electric Vehicle The client had already designed and built a vehicle, so Glew Engineering analyzed an “as built” vehicle. The company hoped to repurpose a float/SUV that they had used previously in parades. Our client was requested by the theme park to repurpose the SUV, and perform cosmetic alterations [...]

Liquid crystal display (LCD) screens are omnipresent in our technologically saturated lives. Having largely displaced the older CRT screens, LCDs make up a large portion of the digital imaging we see all around us. They are present in everything from our ubiquitous smartphones and computer screens to digital billboards, wristwatches and vehicle and aircraft instrumentation. How do flat panel LCD screens work? One can often find videos and articles documenting eager teardowns of new devices, but few delve beyond the hardware and into the materials and design behind the screen itself. For this series of blog posts, we will be review some aspects of display technology , why they work, and how they are assembled. To illustrate my points, I’ve disassembled a legacy Sony Ericsson® S500i phone [...]

The entertainment industry relies on "entertainment engineers," e.g. mechanical engineers, electrical engineers, and others for standards https://www.smpte.org. Perhaps more importantly, the movie industry requires Licensed Mechanical Engineers to safely innovate and amaze. Film sets are complex physical productions, most of which are not digital special effects. The film industry utilizes Licensed Mechanical Engineers to create complex props and various special effects that move, exploded, burn, and fly. The mechanical engineers specializes in designing and making a wide range of mechanical devices that fulfill a specific purpose for the film or set they are engaged, or modify available technology to quickly achieve stupendous results. Licensed Mechanical Engineers also help in structural aspects of heaving rigging, such as lighting (See above Fig. 1 [...]

Mechanical Engineering Consulting Firm Solves an Axle Failure Attorney Requested Mechanical Engineering Consulting and Litigation Support Glew Engineering provides mechanical engineering consulting to high technology and industry. As is often the case, an attorney asked us to provide an independent 3rd party review of the cause of repeated torsion axle failures on a semi-truck trailer that his client experienced. We obtained the failure information and photographs from the client and researched the trailer and its axle configuration. As mechanical design experts, we formulated an unbiased opinion on why the trailer’s axles failed multiple times despite being under the rated loads. For the final phase of our litigation support, we wrote and expert report documenting our findings. Litigation Support [...]
Mechanical Engineering Consultants Use 3D CAD Software Comparison via Custom Motorcycle Frame: Creo vs Solidworks vs Inventor: Part 2Glew Engineering 2018-03-08T12:14:53+00:00
3D CAD Software Comparison Blog Series: Starting the Motorcycle Frame Design in Solidworks™ Welcome back to our 3D CAD software comparison blog series. Recall that in last week’s discussion, as Mechanical Engineering Consultants we introduced our plan to to model a motorcycle frame in three different 3D CAD software packages. We gave a brief history of the three CAD software packages that Glew Engineering employs: Solidworks™, Creo™, and Inventor™. In this week’s blog, as Mechanical Engineering Consultants we use Solidworks™ CAD software to model a portion of the motorcycle frame, a simple tube, while comparing three modeling techniques: Extruding Sweeping Weldment Motorcycle Frames We designed a simple bobber inspired motorcycle frame, this is conceptual, yet realistic enough to illustrate [...]
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 [...]
As energy efficient environmentally conscious engineers, we here at Glew Engineering do what we can to save energy and resources both around home and around the office. This might mean choosing products that are more environmentally friendly or energy efficient. It might mean using our surroundings to our advantage, like pulling cold air through a home or office at night so the building needs less air conditioning the next day. The most satisfying thing, though, is to employ our knowledge of mechanical engineering, materials science and thermal management to design custom hand-tooled solutions. In the next few blog posts, I'll review some of the current in-house engineering projects that are underway here and maybe give our readers a little inspiration [...]
Wind Load Comparison between CFD and ASCE 7 for Rooftop shapes Welcome back to our blog series on the phenomenon called Wind Load CFD Modeling and how it affects civil and mechanical engineers. Wind Load is the force that blowing wind exerts on any device or structure that extends above ground level. After an initial introduction to the factors that affect wind load on an object, I compared three different sets of wind load calculation methods using three simple objects, hypothetically placed on a 100-foot-tall building. Starting with generic drag equation for the first equation, added two modification coefficients called "gust factor" and "exposure coefficient" for the second equation. I used the model for rooftop objects for the [...]
Wind Load Calculation Wind Load Calculation is an overview of the force that blowing wind exerts on a tall object. A number of factors that influence the actual wind load on a real building, include the surrounding terrain, nearby structures, trees, and typical weather patterns for the area. Comparing wind load calculations are most complicated . Calculations try to account for as many of these external factors as possible, to the point where the wind load section in American Society for Civil Engineer’s ASCE 7 standard, spans five chapters and over 100 pages. Fig 1: Wind load calculation example structures ASCE 7's Applications Comparing one of ASCE 7’s Applications with the two equations [...]
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 can have on a structure. Wind load is most commonly addressed by civil and structural engineers when designing buildings, but mechanical engineers can encounter the effect when designing tall objects like cranes, telescoping communications masts or wind turbine towers. Wind Load Essentials As a force, wind load is the product of pressure distributed over an area (psf times ft2 or Pa times m2). In [...]
