Materials and structures
SUPSI Image Focus
Stress-deformation characteristics are determined with innovative equipment in the DynaMat laboratory and state-of-the-art instruments such as the ESPI system for 3D deformation measurement using laser interferometry.
The research and experimentation activities of the Materials and Structures sector are directed towards the study of the mechanical behaviour of structures through the testing of full-scale elements.
The analysis of the failure modes of structures made of both traditional materials (concrete, steel, wood, etc.) and new materials (reinforced with carbon, glass or aramid fibres), in combination with mechanical and environmental ageing, is aimed at reconstructing the actual conditions in which the structures are found in the laboratory.
Materials research focuses on the mechanical characterisation of materials over a wide range of strain rates and temperatures.
Stress-deformation characteristics are determined with innovative equipment in the DynaMat laboratory and state-of-the-art instruments such as the ESPI system for 3D deformation measurement using laser interferometry.
Hydraulic machines (up to 5 MN) with digital measuring chains connected to force, displacement, temperature sensors, etc.
Vibration measurement of structures and identification of eigenfrequencies.
Data and probe control is available remotely via web browser.
The available sensors allow measurement in the 1-315 Hz range.

Material tests
In the DynaMat interdepartmental laboratory there are four Hopkinson bars, two hydropneumatic machines and two universal machines that allow the precise measurement of stress-strain curves of materials in tension, compression and shear over a wide strain rate range from 10-6 to 105 s-1 and over a large temperature range (-100°C to +800°C).Testing of full-scale structures
