In this video snip Greg discusses the difference Craftsmanship can have in CAE (Computer Aided Engineering), specifically highlighting the difference between a Journeyman’s mindset and that of a Craftsman. Greg highlights that in any computer endeavor, it’s always the connection between the keyboard and the seat that makes sure GIGO (Garbage In – Garbage Out) doesn’t apply. Accurate use of FEA (Finite Element Analysis) requires rigour and competence, and it’s passion that makes the difference!

In this video snip Greg takes the opportunity to highlight how even in a seemly simple inbuilt “C” Channel analysis, the assumption of fixity should be questioned. In simple language he discusses the implications of Tx, Ty, Tz, Rx, Ry, Rz Boundary Conditions (BCs, Restraints or Fixtures) common to FEA in the real world, and introduces the concept of sometimes letting the structure take it’s natural shape to develop worst case stresses.

In this video snip Greg explains how 3-2-1 Jig Theory he learned in Boeing helps analysts develop free (unrestrained or natural) deflected shapes in FEMs (Finite Element Models). He uses the example of a simply supported beam and the expectation of a happy (smiley) deflected shape to understand why minimally restrained models often impose the worst case (highest) stress condition and so are at least conservative. He also highlights how important it is to have an expectation of the deflected shape you’re going to see, and stresses somewhere in the model, before running an FEA. He then highlights how difficult it can be in most CADs free (express) FEA add-ons to get even marginally accurate Boundary Conditions (BCs, Restraints or Fixtures).

In this video snip we discuss how Murphy’s Law suggests that if something can happen, it will. And if it does, we want our analyses to have been done on the basis of Worst Case, both in loadings and boundary conditions (BCs, Restraints or Fixtures). Since we can’t always get our boundary conditions accurate enough, remembering that Saint-Venant’s Principle applies can often help us swap loads and boundary conditions to get accuracy where we need it. Also, using 3-2-1 boundary conditions allows us to verify our models simply and quickly. Enjoy!

In this video snip Greg goes into his personal journey and discusses the importance of not just IQ (Intelligence Quotient), but EQ (Emotional Quotient) for engineers. It highlights the best place to improve ourselves is in our personal development. Greg highlights that EQ is about connecting with people. He mentions that through things like the Landmark Forum, the More To Life Weekends and Eckhart Tolle’s books and Nonviolent Communication (NVC) we can enhance our connection with others. And bring our passions to life!

In this guest lecture snippet we highlight the journey that we went on with SATCO to prove upfront our capability. They asked us to show them where their Feller-Delimber was failing in the field before we could offer them a solution… Problem verification and validation, all in one.

We discuss some challenges with flat pattern DXFs when bent in the sheet metal modules of 3D CAD packages, how to develop loads and boundary conditions (restraints) in FEA packages, what Saint-Venant’s Principle offers us, what we discuss in our Computation Solid Mechanics guest lectures including fixtures, worst case loading and singularities in FEA, as well as a great description of how Feller-Delimbers work, and the contribution we provided in resolving some fundamental design issues with the client. Enjoy!

In this guest lecture snippet we highlight the design solution we developed following the problem validation for SATCO. A great journey for both Motovated and the client. We discuss the challenges of doublers and gussets in the load-follows-stiffness concept, which is optimized with monocoque design. We mention Hercules Aerospace’s concept of thousands of solutions but quality is defined by conformance to requirements. We discuss various thermodynamic cycles including Carnot, Brayton, Diesel and Otto cycles as applied to automotive technology. We discuss how it’s about the journey with the client however, not just the design, engineering or the analysis!

In this guest lecture snippet we highlight a way that engineers can help their colleagues and management with their planning.

Excellent learning for all engineers, not just those that aren’t quite sure of what their up to yet!

In this guest lecture snippet we discuss Geoff Henderson’s Windflow 500 two bladed Wind Turbine, including the Torque Limiting Gearbox ™ (TLG) and the Teeter-Control System ™ (TCS). We highlight the opportunities that come from failures, including the Gebbies Pass back winding event, and the highly non-linear dynamic analyses we ran to resolve the bolted joint issues between the gearbox and the tower. We also discuss the energy absorbing qualities of bolted joints, and the value of long bolts in the context of dynamic analysis. Another amazing journey with our clients, enjoy!

In this guest lecture Greg discusses why he chose to develop Motovated Design & Analysis. While we’ve snipped out the back story of growing up in Alaska and working as a snowmobile, motorcycle and automotive mechanic before attending University and working for Hercules Aerospace and Boeing, we do explain that mechanical engineering is much more efficient with a little bit of analysis. And that in mechanical designs, a little bit of analysis goes a long way! Pareto Principle on steroids! 10% of the analysis done for Boeing or Hercules gets our clients 90% of the value we supplied to them. We discuss being a leading provider of computational solid mechanics, including MathCAD, FEA and CFD, as they are applied to actual real world machine design. We highlight that phenomenal engineering is our passion, and helping inventors and manufactures realize their dreams is why we exist as a firm. Enjoy!
