Guest-speaker: Suction pile foundation design in OPTUM G2 and OPTUM G3

We are very excited to announce our upcoming webinar on the topic “Suction pile foundation design in OPTUM G2 and OPTUM G3” hosted by guest-speaker Christian Linde Olsen from Subsea 7. Subsea 7 is a subsea engineering, construction and services company serving the offshore energy industry. Christian will show how Subsea 7 make use of the Finite Element Limit Analysis capabilities in OPTUM G3 and compare analysis results with data from a recently recovered suction pile structure. During the presentation, Christian will demonstrate the advantages of performing a 3D analysis on a template with suction piles.

The 45 min webinar will be followed by a Q&A with Christian and the Optum founders.

Guest-speaker: Design of rock anchors for offshore applications

While grouted rock anchors are common in engineering practice, the design of groutless anchors relies on oversimplified design methods. Dr. Benjamin Cerfontaine of University of Dundee will present his use of the Optum software in his research and why limit analysis is the perfect technique to efficiently investigate the failure mechanisms of groutless anchors and identify variables that should be incorporated in more accurate design methods.

Torsional loading effects on bearing capacity of shallow foundations in G3

In this webinar hosted by Optum co-founder Prof Kristian Krabbenhoft, we will show how OPTUM G3 can be used for evaluating the bearing capacity of shallow foundations with torsional loads. We will explore the effects of the FASD Sand model on the bearing capacity and also show how Matlab scripting can be used to effectively create failure envelopes (V-H, T-V, etc).

Guest-speaker: The use of limit analysis in tectonic studies

Below temperatures of 300 °C, at depths lesser than 10 km, rocks are frictional Coulomb materials.
Therefore, Limit Analysis offers a useful simplified theoretical approach to the study of shallow tectonic deformations.

Pr. Bertrand Maillot of Géosciences et Environnement Cergy (GEC) presents various examples of such studies in this 45 min webinar followed by a Q&A with Bertrand and the Optum CE founders.

The bearing capacity equation and how well it fits with Optum 

A question we often get from users is why they are getting different results when using the bearing capacity equation and Optum. For some cases  the bearing capacity equations provides exact results which is very valuable for verification purposes. For most cases the bearing equation is not exact, but in fact still very precise, which makes it useful for design but also for verifications. Find out for which cases you can expect perfect agreement, and for the cases you cannot: Why and What is the difference?

Guest-speaker: 3D analysis in offshore geotechnics

45 min webinar hosted by guest-speaker Christian Linde Olsen from Subsea 7 followed by Q&A with Christian and the Optum CE founders. Subsea 7 is a subsea engineering, construction and services company serving the offshore energy industry. Christian will present their use of 3D analysis with 3 examples, one of which is the case study "Lessons Learned - Counter-acts Used To Install Pipelines Offshore In Very Soft Clay" and compare the results to OPTUM G3 analysis.

How to choose the right friction angle in 3D

When doing 3D FE calculations you need to decide on which friction angle to use: Should you use the Plane Strain friction angle or the Triaxial friction angle? As the friction angle is dependent on the stress state the answer is not that easy. In OPTUM G3 we have found the solution to the problem and invite you to watch this webinar for the first-ever presentation of our new sand model.

Consistent undrained modelling of clays in OPTUM G2 and G3

What to do when Tresca is a poor fit? As you might have discovered, real life clay has more to it than a single value. In OPTUM G2 and G3 all scenarios are easily handled using our material model called AUS – Anisotropic Undrained Shear – which – despite it’s name – actually handles both isotropic as well as anisotropic clays. Please join and learn how the AUS material model can be used for both Limit Analysis calculations, as well as for determining load-displacement curve.

Slope stability in OPTUM G2

In OPTUM G2, factors of safety are computed using Strength Reduction Finite Element Limit Analysis (SR-FELA). Besides short calculation times, SR-FELA also provides the possibility to calculate rigorous upper and lower bounds on the true factor of safety. In practice, this means that the true factor of safety can be determined within a negligible tolerance in a matter of seconds.

Retaining walls in OPTUM G2

Retaining walls come in a wide variety of types including mass gravity walls, mechanically stabilized earth walls, gabion walls and sheet pile walls. All of these can be analysed efficiently and accurately using OPTUM G2. The unique ability to compute rigorous upper and lower bounds on the true Factor of Safety (FoS), combined with automatic mesh adaptivity, makes OPTUM G2 a superior tool for design of retaining walls.
