Experimental technology placement in the Operational stability and structural component optimization laboratory:

  • Experimental tension analysis using the strain gauge (DMS).
  • Measuring material damping.
  • Recording cyclical flow curves for the over-elastic finite element (FE) calculation of near-net shape notched samples. Comparison of FE results and analytically approximated notch strain values with strain measurements.

Climate technology laboratory

The Climate technology laboratory provides access to an extensive range of measuring equipment to measure all relevant quantities in the area of climate technology.

The fundamental experimental structure within the climate laboratory is a climate chamber. This is subdivided by a separation wall into two equally sized zones – the interior climate zone and the exterior climate zone. Different atmospheric conditions can be achieved in both zones. Both chambers can be accessed from outside by two separate doors. It is possible to create a separation wall by installing construction elements, such as windows, façade elements, doors or similar, without a great deal of effort.

The properties of the climate chambers are as follows:

Measurement technology laboratory

Lab rooms: KA.009, KA.011, KA.U20, KA.U22

The Measurement technology laboratory is used by students during their studies. This applies to the lectures teaching the basics of measurement technology, but the laboratory is also used to carry out scientific work in the context of projects, or bachelor’s or master’s theses. Furthermore, collaborations with industry are also maintained.

To complement their studies, students in the MB, EGT, and IBT bachelor's degree programmes have a compulsory placement in measurement technology. Students are familiarized with the conventional configurations used in measurement technology, with an emphasis on applied measurement technology. During the placement, students are trained in the safe handling of sensors and measurement systems in a practical context. An important feature of the training is to correctly determine temperatures, lengths, routes, forces, momentums, deformations, quantities expressing atmospheric conditions, speeds, and many other quantities within a wide diversity of test rigs. In smaller projects, students are required to apply what they have learned autonomously. To that end, test rigs such as home training apparatus, air compressors, cableways, espresso machines, air conditioning systems, and others are available for students to use.

Computer-aided design laboratory

In the Faculty’s Computer-aided design laboratory from the first semester onwards, students follow a number of consecutive courses that familiarize them with the methods and systems of computer-aided product development (CAD/CAE) and production (CAD/CAM/CAP). The main activity for which the CAD laboratory is used is for the courses CAD 1” and “CAD 2, and in order to produce the design engineering projects required in the courses Design Engineering 1 and Design Engineering 2 and for the design and development project. The laboratory is also used for a variety of bachelor’s and master’s degree theses.

The computer pool encompassing all laboratories currently consists of 166 workstations, on which a large number of program packages for design and calculation are available (analytical and FEM).

The opening hours of the laboratories and the room schedules can be found on the THN intranet.


Disciplines that form part of computer-aided design

CAE = computer-aided engineering
CAE is defined as the computer-aided solution of technical and scientific problems before and during the engineering stage of the development and construction process. It encompasses many sub-areas, such as CAD, FEM, CFD, MKS, FSI, CAM and CAQ.

Engineering Design, CAD, and Simulation

CAD (= computer-aided design) encompasses all activities that make use of electronic data processing in the context of development and design work.
Thanks to the range of functions and tasks it is capable of carrying out, the CAD system is one of the key components of a computer-integrated production and of the digital product model, when the aim is to achieve a faithful description of a product in the computer, along with all of the relevant documents, attributes, and structures.


The Finite Elements Method (FEM) is a numerical process to solve partial differential equations.
FEM is primarily used in order to mathematically define the elastic properties, and if applicable the plastic properties of mechanical systems in which mass and elasticity are continually distributed across the bodies. In such cases, the model consists of many finite elements of simple geometry, whose principal deformation capabilities are restricted by the specification of trial functions. The objectives of the examinations are primarily the effects of external loads on the deformation and tension conditions in the bodies concerned. The mathematical formulation of FEM systems results in ordinary differential equation systems incorporating a very large number of degrees of freedom.


The objective of computational fluid mechanics (CFD) is to resolve fluid dynamics problems using numerical methods.


Multi-body simulation (MKS) is suitable for describing mechanical systems consisting of bodies that largely behave rigidly and are connected to one another by means of bearings and joints. An MKS consists of generally rigid bodies impacted upon by individual forces and moments at discrete points.


FSI stands for Fluid Structure Interaction and refers to the linking of flow and structural calculations, in order to calculate the mutual influence that takes place.


CAM stands for Computer-Aided Manufacturing and refers to the EDP-based support that is used to control and monitor the production process. This relates to the control of machine tools, handling devices, and transportation and storage systems. One example of this is the production of NC programs for CNC machines on the computer.


CAQ stands for Computer-Aided Quality Assurance. It forms part of quality management and encompasses measures for the planning and implementation of quality assurance. This includes the drawing up of test plans and test programs and the implementation of computer-aided measurement and testing processes.


CIM stands for Computer-Integrated Manufacturing and is defined as the integrated use of EDP in all areas of production. This includes all activities starting from development and design through to production and quality assurance. The tasks relating to order processing, such as planning, production control, drawing up tenders, and cost calculations will be included.

Materials engineering laboratory I

Lab rooms: KH.U01, KH.U02, KH.U03, KH.012, KH.116

The use of state-of-the-art, high-performance materials is one of the drivers of technological development and plays an important role in innovative technologies of the future. The ability to handle the key technological components used in materials engineering is heavily dependent on a solid understanding of the principles of materials engineering itself. On a practical level, a good understanding of the associations between the (micro) structure of a material and the physical and technical properties of that material is highly important to engineers. For that reason, during the degree programmes students are provided clear demonstrations of materials science knowledge regarding structure, processing, the targeted changing of properties, and testing in practically oriented experiments in the laboratory.

The Materials engineering laboratory I encompasses the most important processes for the destructive and non-destructive testing of materials and material properties. In the laboratory, students are shown how these are used in professional contexts for purposes such as quality assurance, material and product development, and damage analysis, by means of targeted practical exercises on heat-treated, cold-worked, cast, or welded samples.

The primary areas covered include:

  • The application of various testing techniques
  • The interconnection between the structure of a material and its properties
  • The parameters affecting the behaviour of materials and components under static and dynamic load
  • Quality assurance: Detecting and assessing flaws in the material

The laboratory supports companies within the region, fulfilling the role of a partner for tasks in the area of material development and in the carrying out of inspection or testing orders.
