To learn more about how to protect cities, buildings and structures against bombs and terrorist attacks, based NTNU in the New Year with 25-meter test tube.
shock tube, which tube is called, must be applied high pressure to give researchers better understand how various objects respond to physical stresses.

Lack of expertise
– We have too little knowledge about what the consequences of this kind of events is, says Professor Magnus Langseth, by SIMLab at NTNU.
Langseth work regularly with structural engineering, and believes the focus on safety in Norway is low.
– It is bad that it needs an event like the terrorist attack on 22 July, in order for it to be allocated more funds for research on objects, he says.
shock tube will be used for both research and teaching at the school in the future.

Important analysis
Although the test tube is not more than 25 meters long, with a diameter of 30 centimeters, according to the Langseth could provide important information about how objects respond to physical strains of life.
– When a charge is detonated occurs a shock wave that goes into the air and eventually hit all structures nearby. We want to study how objects and components behave in controlled conditions. That way we can prepare the basis for analysis models that can be used to calculate the behavior of buildings, he explains.
During the experiments, use fast film cameras that take up to 1 million frames per second.
– Then we filmed all the action, and can spend time analyzing the experiment in retrospect, says Langseth.

Topical security
funded in cooperation between NTNU, SFI SIMLab and National Security Authority (NSM). Funding for construction of the shock tube is 2 million in 2013. Then NSM supports SIM lab over an eight-year period with 1 million a year until 2022.
funding until 2022 is related to an application from SIMLab of a new center for research based innovation, CASA, including the process object security.
– Object Security is more relevant now than it was before. When the bomb went off in the government quarter 22 July we were reminded of the terrorist threat could previously only seen internationally, but largely also applies to Norway, says Director Carsten Rapp in NSM.
Simplifies control
NSM is responsible for advising on and supervising the object security in Norway. Through support for the construction of a shock tube and participation in CASA will develop expertise in Norway on site as well as control and order various types of tests.
– Directorate will include use tests to verify how various safeguards and materials respond to physical stresses such as explosions, projectiles and collisions. In addition, as will those who control measures easier to check if they have the security they should have, and which they were intended, explains Rapp.
