    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive joining; Dynamic fracture; Cohesive zone; Interphase Element; Bimaterial joining; Hybrid joints; Materials science; Teknisk materialvetenskap; Teknik; Technology;

    Abstract : Today, crash simulations replace crash testing in the product development phase in theautomotive industry. High quality simulations enable shorter product development time andhigher competitiveness. READ MORE

  4. 2. Metamodel-Based Multidisciplinary Design Optimization of Automotive Structures

    Author : Ann-Britt Ryberg; Larsgunnar Nilsson; Anirban Basudhar; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multidisciplinary design optimization MDO ; metamodel; artificial neural network ANN ; support vector machine SVM ; sequential sampling; crashworthiness; automotive structure; spot weld optimization;

    Abstract : Multidisciplinary design optimization (MDO) can be used in computer aided engineering (CAE) to efficiently improve and balance performance of automotive structures. However, large-scale MDO is not yet generally integrated within automotive product development due to several challenges, of which excessive computing times is the most important one. READ MORE

  5. 3. RoPax Ship Collision – a Methodology for Survivability Analysis

    Author : Per Hogström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear FEA; failure modelling; uncertainty analysis; Crashworthiness; sheet metal failure; ship collision; damage stability;

    Abstract : Throughout the world, ships are continuously being declared as total losses and 10 to 15% of these accidents are collisions between ships. The consequences of a collision are diverse and depend on the ship type, e.g. oil outflow in the case of damaged tankers or loss of stability in damaged passenger ships. READ MORE

  6. 4. Pre-Crash and In-Crash Car Occupant Safety Assessment

    Author : Alexandros Leledakis; Chalmers tekniska högskola; []

    Abstract : Tens of millions are annually injured in Road Traffic Accidents (RTAs) worldwide, while the estimated number of RTA fatalities amounted to 1.35 million in 2016. In Europe, car occupants hold the largest share (48%) of fatalities among all road users. The high fatality and injury numbers motivate the work of enhancing road traffic safety. READ MORE
