  2. 16. Material characterisation for crash modelling of composites

    Author : Thomas Bru; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical testing; finite element analysis FEA ; non-crimp fabric NCF ; damage mechanics; carbon fibre composite; crushing;

    Abstract : The transport industry must find solutions to reduce its impact on climate change. A promising way to reduce the weight of vehicles and therefore to reduce the CO2 emissions is to introduce components made of lightweight composite materials, in particular carbon fibre reinforced plastics (CFRPs).

  4. 17. On Lateral Stability of Heavy Vehicle Combinations - Linking Accident Analysis and Vehicle Dynamics

    Author : Sogol Kharrazi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accident Analysis; Vehicle Dynamics; Performance Measures; Lateral Stability Control; Heavy Trucks; Lateral Instability;

    Abstract : One of the hazardous motions of heavy trucks is lateral instability which can be defined as deviation from driver intended path due to skidding of the vehicle. Lateral instability is associated with 9% of heavy trucks involved in traffic accidents, which represents a considerable figure when translated to real accidents. READ MORE

  5. 18. Structural Interaction between Vehicles. An Investigation of Crash Compatibility between Cars and Heavy Goods Vehicles

    Author : Aleksandra Krusper; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Front Underrun Protection; simulation; Heavy Goods Vehicles; compatibility assessment; FUPD; Front Underrun Protective Device; energy absorption; crash compatibility; HGV; structural interaction; FUP;

    Abstract : While frontal collisions between Heavy Goods Vehicles (HGVs) and passenger cars are rarecompared to car-to-car frontal crashes, they are much more severe. Between 43% and 73% ofall frontal car-to-truck accidents result in fatalities. READ MORE

  6. 19. ST analysis of the fetal ECG as an adjunct to fetal heart rate monitoring in labour-a clinical validation

    Author : Håkan Noren; Göteborgs universitet; []
    Keywords : fetal ECG; ST analysis; electronic fetal monitoring; cardiotocography; fetal blood sampling; metabolic acidosis;

    Abstract : The ability to make an accurate assessment of fetal well-being during labour is a great challenge. Animal and human studies have shown that fetal hypoxemia during labour can alter the shape of the fetal electrocardiogram (FECG) waveform, notable elevation of the T-wave and depression of the ST segment.

  7. 20. Thoracic injuries in frontal car crashes: risk assessment using a finite element human body model

    Author : Manuel Mendoza-Vazquez; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element; Thoracic injury criteria; rib fracture; human body model; real-world crash data; survival analysis;

    Abstract : Accident data show that there is a clear need to improve the protection to occupants’ thorax in frontal car crashes. For this purpose, models that can predict the risk of injuries and assess the occupant protection offered by different restraint systems are needed. READ MORE
