   Abstract : Introduction Concussion is an increasing concern in soccer, a sport where players actively use their heads as a part of the game without being required to wear protective headgear. Protective headgear is available but studies disagree about their effectiveness. READ MORE

4. 3. Acoustic emission methods in fatigue testing

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Axel Lison Almkvist; [2015]
   Keywords : Acoustic emission; AE; grey iron; CFRP; Akustisk emission; AE; gråjärn; CFRP;

   Abstract : Acoustic emissions are small vibration pulses, elastic waves, emitted from damage processes such as crack growth inside a material. Acoustic emission (AE) is also the name of the test method in which theses emissions are recorded and analysed and the method is used in materials research and the testing and inspection of structures.

5. 4. Examining the quality of extruded plastic with the nondestructive testing method NAW

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Eva Jansson; Seyed Saeid Taghavi; [2014]
   Keywords : NAW®-method; Nondestructive Testing; Nonlinear Acoustics; Material Testing; Plastic; Ultrasonic Testing;

   Abstract : Defects in a plastic floor material produced in Tarketts factory in Ronneby are causing waste of time and material since it is noticed too late in the production line. The objective of this thesis is to investigate if the nondestructive test method NAW®, which is developed by Acoustic Agree in Ronneby, can be a solution to find the defects at an earlier stage.
