It’s a new era of technology. AI and machine learning have progressed a lot while we still use conventional methods and in many cases highly conservative methods. At Stressman Engineering we always want to challenge the status quo. Together with Peter Smith (Stressman), Patrick Bangart (VP of Samsung AI), and Ben Eckenfels (Algorithmica Technologies) we […]
Stress analysis: What’s the purpose?
By definition, stress-strain analysis (or stress analysis) is an engineering discipline that uses many methods to determine the stresses and strains in materials and structures subjected to forces. Stress analysis provides great insight into the mechanics of a solid. It can help engineers determine how products will perform throughout their lifetimes. The topmost for Stressman […]
ASME BPVC Section VIII, Division 1 – 2019 Edition
The ASME Boiler and Pressure Vessel Code (BPVC) is an American Society of Mechanical Engineers (ASME) standard that provides rules for the design, fabrication, and inspection of boilers and pressure vessels. The codes consist of the following sections: • Section I: Rules for construction of power boilers.• Section II: Material specifications.• Section III: Rules for construction of […]
Three-point Hitch
In Stressman engineering we like to look at components from a global perspective. Simple components just interacting with a couple of other components can at first look easy to analyze locally. Traditionally systems are broken down into smaller sub-systems and analyzed separately. This is still in use today, and still will be for a long […]
DNV has presented the new DNV-ST-F101 Edition 2021
As a result of the continuous improvement of submarine pipeline systems design, a new version of the DNVGL-ST-F101 has been released by DNV to supersede the October 2017 edition. The first visible change is the new acronym of the standard due to the rebranding of DNVGL to DNV. This popular standard has been improved over […]
Upheaval Buckling (UHB)
At Stressman we are aware of the major concerns for subsea hydrocarbon pipelines design. One of the major issues for subsea pipelines subjected to high pressure and temperature conditions is upheaval buckling (UHB). UHB occurs when the pipeline moves upward and loses contact with the seabed creating a large transverse deformation driven by the effective […]
The plastic capacity of a profile
A test comparing plastic capacity in welded profiles when analysis with or without welds+ analyzing as simplified shell element. Profile with welds Profile without welds Shell element Geometry Profile with welds Profile without welds Shell element Conclusion Analyzing steel structures from plates/sheet metal with simplified contacts and shell elements does not significantly impact the plastic […]
The Varodd Bridge in Agder
Team Stressman in collaboration with Vinje Industri AS was engaged into the challenging project of dismantling the Varodd Bridge from the design of the equipment employed for the deconstructing activities until the analysis of the lifting operations to remove sections of the bridge. The goal of the project was to analyze and validate the components […]
Thrust Blocks
Thrust blocks prevent buried piping from moving when pressure and thermal load are applied. In effect, thrust blocks transfer the load from the pipe to a wider load-bearing surface. Thrust blocks are required where fittings are used to change the direction (i.e., at ties, elbows, wyes, caps, valves, hydrants, and reducers) of buried piping systems. […]
Consequences of removing rounded edges on hollow profiles
Rectangular hollow sections are often used in structures. When presented with these profiles in FEA one can be tempted to remove the rounded edges but what are the benefits and what are the consequences of doing so? In this article, the second moment of area of the rectangular hollow section will be compared (with and […]
