Photoelasticity is a proven method of analysing and recording mechanical stresses and strains in components. It is used both for quantitative measurements and for demonstrating complex stress states. The components used are models made of a transparent, photoelastically sensitive plastic, which becomes optically birefringent under mechanical load.

Photoelasticity can be used to demonstrate stress profiles and stress concentrations in component models.The distribution of stress in plane, transparent bodies (plastic models) is investigated using polarised light. Polarising filters represent the stress profiles in colour. The notching and point loading and the criteria dictating component design are clearly visualised.

This system for data acquisition is an addition to the TM 150 vibration trainer and makes it possible to analyse vibration signals on a PC. Frequency and phase response curves can be easily generated, saved and output using this system. The system also offers all the essential functions of a digital storage oscilloscope and can calculate the frequency spectra of the signals.

WP120 - WP121

In engineering mechanics, loss of stability is known as buckling. The bar axis laterally deflects under the effect of compressive forces and with increasing load until it suddenly and violently fails, just before the fracture strength is reached. The stresses in the bar are often still in the elastic region. WP 120 investigates the buckling behaviour of bars under different influences.

In stability theory, the four cases of Euler buckling represent the elastic flexural buckling of straight bars. Above a specific load – the buckling load – a loss of stability occurs and the bar increasingly changes shape. The axis of the bar is deflected laterally. Euler describes four cases for the buckling of an elastic bar with central application of compressive force and various methods of support.WP 121 demonstrates the four cases of Euler buckling. Depending on the end conditions, different weights are required until the buckling load is reached and the axes of the bars are laterally deflected.

WP300 - WP310 - WP400 - SE100

A solid understanding of the properties of materials is essential for technical and scientific professions. This knowledge helps select the suitable material, monitor production and processing and ensure the requirements in terms of a component. The materials test provides the necessary data in a reproducible and precisely quantified manner. The tensile test, bending test and hardness test are all part of classic destructive materials testing.The range of experiments with WP 300 covers tensile tests and Brinell hardness tests in the base unit.

A classic discipline of materials testing is the destructive testing method, in which specimens are mechanically tested to failure. The materials test provides data for hardness, rigidity and strength in a reproducible and precisely quantified manner.The WP 310 unit, in conjunction with the accessories, offers experiments from destructive materials testing

In the field of industrial quality control, the impact test is a widely used test method with which to quickly and easily determine characteristics for a material or component analysis.The WP 400 experimental unit is a solid-pendulum impact tester based on DIN EN ISO 148-1, designed for the Charpy notched-bar impact test. The clean layout and simple operation mean the experimental sequence can be observed in all details and phases.

The demands of modern, technically sophisticated designs require a solid understanding of the strength and deformation of components. Different load states can be simulated in load experiments and the reaction to the load recorded and analysed. This makes it possible to demonstrate the load bearing capacity of the design by means of experiment. The SE 100 frame for load tests has been designed specifically for experiments in the fields of steelwork and civil engineering. Large components at a 1:1 scale are studied.
