We continually updating updated our Events Page concerning engineering conferences.

Bill O’Donnell, Sr., recently published “Handbook of Lessons Learned In Engineering, Design, Manufacturing and Construction.” It is intended for engineers, designers, manufacturers and constructors – depicting failures from thermal, structural, vibration, corrosion and other failure mechanisms. Read a sample of this book, Section 1 Designers’ Lessons. This book can be purchased at Amazon.com.

Check out our Portfolio Page of projects – we are continually adding to it. Above is a model for a base skid containing a Vapor Recovery Unit that we performed a structural analysis.

FEA Model of Feedwater Heater   FEA Model of Pressure Vessel   Blog – Finite Element Analysis (FEA) What is finite element analysis? Finite element analysis (FEA) is a computer simulation method useful for the evaluation of components, structures and systems. It is a versatile and powerful tool that models simple and complex geometries, in …

Stress and Fatigue Analysis of Bellows    What in the World is a Primary Stress? Most engineers are familiar with the terms “Normal Stress”, “Shear Stress” and potentially “Equivalent Stress”, however perhaps not so much with the terms “Primary Stress” and “Secondary Stress”. What do these terms mean and why are they important? “Primary Stress” …

The reliability and integrity of equipment, structures and piping can suffer because of vibration and dynamic responses. These depend mainly on excitation forces, stiffness, mass distribution and damping. Modal analysis, which focuses on natural frequencies and associated modal shapes, provides an important tool in understanding potential issues. Indeed, usually the first step in checking for …
