The DRG lectures are an annual series of lectures for stress and mechanical engineers in The Netherlands. The lectures are a platform to discuss technical subjects and are followed by a reception to continue the discussion on an informal level.


The lectures are open to all stress and mechanical engineers at no cost. Drinks are included.


The lectures will start at 16:00 hours and last till approximately 18:00 hours.

Previous Lectures

Since 2007, DRG has hosted a large number of lectures for an audience of stress and mechanical engineers. With around four lectures a year, many subjects have been presented and have often been followed-up by a lively discussion during the informal drinks afterwards.


The latest lectures are found below and an overview of lectures of previous years can be viewed here. If available, the lecture notes can be downloaded, or – for the more recent lectures – the lecture can be viewed online.

Dynaflow Conference 2015


The 3rd DRG Conference in the Netherlands on Flow Problems in Oil & Gas Industry was held September 23rd 2015.


During the morning training sessions two groups gained basic insight in the use of HELYX® CFD and our in-house software package BOSfluids®. In the afternoon five presentation were given covering a broad spectrum of fluid flow problems related to multiphase flow assurance, pressure surges in pipelines and flow induced vibrations, etc.


The presentations can be viewed here.

Lectures 2015

Dynamic Stress Analysis. How to deal with AIV, blast loads, thermal transients, surge, vibrations, pulsations and other transient effects


Speaker: Richard Fawcett of Dynaflow Research Group


In this lecture a range of transient effects will be introduced. It will be shown why they occur and what their effect on a stress analysis is. A number of typical projects conducted by DRG will be used to demostrate how these transient effects can be included in a stress analysis.
