Design with Finite Elements

The education part is the exact content of the lecture wb3416 “Design with Finite elements” or with the new course code ME44105 of Wouter van den Bos at the Technical University Delft (TU Delft). (3 ECTS points). If you have a (trial) license of both FEMAP and SDC Verifier  you can follow this course on your own.

For non-TU Delft students who would like to follow the course (for example if you want to join the European ERASMUS exchange program) and use the ECTS points for your own study, leave your contact details here, and we will explain the possibilities. For TU Delft students please directly follow links below for direct viewing of the lectures or course overview per topic. More information can be found on  the Brightspace page of the course (You need a TU Delft account to see the content)

Course content:

This course is an excellent introduction to FEA how to verify the large number of load combinations and how to calculate according to standards. For this course the (old) crane standard NEN2018 and NEN2019 is used. This standard is almost identical to the FEM 1.001 and DIN 15018. Although nowadays the more modern standard EN13001 becomes more popular, it is a relative easy norm to understand and therefor perfect for educational purposes.

General Purpose of the course

The course ME44105 is based on the previous course wb3416 Design with FEM. The main goal for the course Structural Design with FEM is to learn using FEM (Finite Element Modeling) software as a design tool. The assignment for this course is to structurally design a crane with the aid of finite element program FEMAP and calculate loads with SDC Verifier. Choose a crane (or ship loader / unloader) from a library of example cranes and structurally design the crane with the information given from the technical specifications sheet and a photo or basic design drawing of an existing crane.

Starting from the basic layout of the crane (see the photo) the structural design of the crane has to withstand weather conditions and the working loads given in the specifications. In order to study the influences of the different loads and conditions a finite element model of the crane has to be made. For 1 detail a plate buckling analysis has to be compared with the theory.

For approval the crane has to be calculated according to the Dutch standards NEN 2018 and NEN 2019. For this course at least the following criteria have to be checked:

  • Material stress
  • Fatigue
  • Corner loads
  • Deflection
  • Eigen frequencies
  • Buckling

All of these according to the criteria set by the standard.
