The Fraunhofer Institute for Short-Term Dynamics, Ernst Mach Institute (EMI, shortened to “Fraunhofer EMI”) is an institute of the Fraunhofer Society for the Promotion of Applied Research e. V. It was founded in 1959 by Hubert Schardin in Freiburg im Breisgau .

The activities of the institute are assigned to applied research and development in the field of engineering in the fields of shock wave and impact physics, materials science , computational physics and short-term measurement technology. In addition to the location in Freiburg, there are the institute parts Efringen-Kirchen and Kandern .

The epithet "Ernst Mach Institute" is named after the physicist Ernst Mach (1838–1916), who for the first time succeeded in using short-term photographic methods for visualization to make ballistic and gas-dynamic processes visible.

Research and Development

The Fraunhofer EMI is an institute that deals with a wide range of topics from applied physics and the investigation of physical-technical processes in materials, structures and components. It specializes in the investigation of physical-technical processes in materials, structures and components. The research work of the EMI lies in its business fields of defense , security , automotive , space travel and aviation and aims to increase the security, reliability, resilience and sustainability of society.

The research profile includes materials science , ballistronics (coupling of ballistics and microelectronics or micromechanics ), high-performance computing , sensor technology and short-term measurement technology . Research and development is in the areas of security of infrastructures , traffic safety technology, protection technologies for space vehicles, analysis of incidents, use and effects of explosives, civil and military protection technology.

A wide range of methods is available for recording short-term processes that enable the measurement and visualization of processes that take place in the time range from milliseconds to nanoseconds , at high pressures of up to 1 megabar and at extremely high expansion rates of up to 10 ⁶ s ⁻¹ .

For example, high-speed cameras, bright pulsed light sources, laser stroboscopy and X-ray flash technology are used to record the short-term processes. In the test facilities of the Fraunhofer Institute, material properties can also be tested under highly dynamic conditions and suitable descriptions can be defined for the simulation.

Fraunhofer EMI has several acceleration systems with which projectiles can be accelerated to high speeds. The two-stage acceleration facility in Efringen-Kirchen is the largest in Europe. In addition, the institute is a recognized test center for standard tests of explosion-resistant safety glazing in accordance with DIN EN 13541 . The properties to be taken into account for a CE marking are specified in Annex ZA of the respective product standard.

Cooperations

Fraunhofer EMI is a member of various Fraunhofer groups and Fraunhofer alliances. The Fraunhofer institutes bundle their respective competencies and make it possible to find competent contact persons for complex tasks, who can develop cross-institute solutions and coordinate research and development.

Fraunhofer EMI is a member of the following Fraunhofer networks

• MATERIALS
  This association bundles the competencies of the twelve institutes of the Fraunhofer-Gesellschaft with a focus on materials science .
• Fraunhofer
  Group for Defense and Security Research VVS In this group, Fraunhofer institutes have come together to coordinate and implement their research activities in the field of "Defense and Security".

Fraunhofer EMI is a member of the following Fraunhofer alliances

• Fraunhofer Alliance Numerical Simulation of Products and Processes
  Twenty Fraunhofer Institutes bundle their competencies here, which deal with the development and improvement of simulation processes.
• Fraunhofer Building Alliance
  The alliance offers building expertise from a single source through integral system solutions for the construction industry. Twenty Fraunhofer institutes bundle their competencies here, which deal with the development and improvement of simulation processes.
• Fraunhofer Lightweight Construction Alliance
  The institutes combined in the Fraunhofer Lightweight Construction Alliance have competencies in the areas of materials and material composites for lightweight construction, joining and manufacturing processes in lightweight construction, numerical and experimental simulation in lightweight construction and evaluation of components and systems.
• Fraunhofer Battery Alliance
  The focus of the research work of this Fraunhofer Alliance is on batteries and supercapacitors, including redox flow systems; the value chain extends from materials for even the smallest storage units to module structure and battery management to quality assurance in production and the simulation of Materials to designs.
• Fraunhofer Space Alliance
  The Fraunhofer Space Alliance is an amalgamation of institutes that conduct applied research for space in the field of space technology.
• Fraunhofer additive manufacturing alliance
  The Fraunhofer additive manufacturing alliance integrates 15 Fraunhofer institutes across Germany, which - with a focus on different areas - deal with the subject of additive manufacturing, thereby mapping the entire process chain. This includes the development, application and implementation of additive manufacturing methods and processes as well as the associated materials.

Together with Gunther Neuhaus , Vice President Research at the Albert Ludwig University of Freiburg, Stefan Hiermaier is the coordinator of the Sustainability Center, a cooperation between the five Freiburg Fraunhofer Institutes and the Albert Ludwig University.

Since 2015 Stefan Hiermaier has been director of the Institute for Sustainable Engineering Systems (INATECH) at the Technical Faculty of the University of Freiburg.

Since 2006 there has been a cooperation with the Institute for Mechanics and Statics of the Faculty of Civil Engineering and Surveying (now Faculty of Civil Engineering and Environmental Sciences) at the University of the Federal Armed Forces in Munich . The aim of this cooperation is the joint expansion of international research projects and an increased technology transfer of research results to subsequent products.

Infrastructure

• In 2015, a total of 330 people were employed at EMI, more than half of whom work in the scientific and technical field.
• The operating budget of Fraunhofer EMI in the 2015 financial year was 27.3 million euros.
• Stefan Hiermaier has been the head of EMI since January 1st, 2015. At the same time, since January 1, 2015, he has also been the director of the newly founded Institute for Sustainable Engineering Systems (INATECH) at the Technical Faculty of the University of Freiburg. Hiermaier has been working at the Ernst Mach Institute since 1996. He was appointed to the adjunct professorship for high dynamics at the University of the Federal Armed Forces in 2008.
