Book Description
Side impact car crashes account for roughly 30% of all fatalities in road accidents including passenger cars and light trucks, and they tend to have a disastrous effect on the human body than all other types of car accidents due to very less crumple zone. In consideration of all this, even in the lower end and higher end vehicle segments, active safety systems are incorporated more often for side impact protection. However, there is still a large number of vehicles built without side airbags, in specific regions such as North America and emerging markets. Therefore, it is still necessary to engineer passive safety measurement by utilizing safety countermeasures, such as foams solutions to protect the occupant during side impact collisions. The present study is focused on investigation of the advantage of applying high efficient energy absorption foams for side impact protection of car occupants. First, the characteristics of high energy absorbing foam models are examined by finite element analysis and simulations of the Drop Tower Tests and the Free Motion Headform tests. After ensuring material models behavior, the design of the current B-pillar is altered by adding foam into its cavity. Subsequently, side impact test simulations of a typical passenger car with a moving deformable barrier, as per NHTSA and IIHS safety regulations, with the current and modified B-pillar are conducted. In the end, various injury criteria are evaluated by positioning a ES-2re finite element dummy model with, a three-point lap and shoulder seat belt into the driver seat. The study demonstrates that the potential for the use of high-energy absorbing foam for side impact protection.

Book Description
The automotive industry is repeatedly tasked with improving vehicles structural strength, optimizing active and passive safety features, reducing occupant injury potential, and hitting lean manufacturing goals. The challenge is to find solutions to reduce production and research costs, and to maximize the vehicle's capability in protecting its occupants in the event of an accident. The influence of impact loading on the dynamic responses of vehicle structures and occupants require special consideration in the field of vehicle crashworthiness. The main goal of this study is to address the fundamental aspect on the impact injury biomechanics of vehicle occupants and safety performance of vehicle structures, and the development of various new technologies aimed at enhancing the passive safety of road vehicles in side-impact accidents. Four case studies related to the dissipation of crash energy, impact injury biomechanics, injury prediction model and pre-crash sensing algorithm form the basis of this thesis. The application examples include the investigation of pre-deploying airbags as a potential solution in reducing occupants' injuries at higher speed side-impact crashes; examination of the vehicle structural responses with the inclusion of high-energy absorbing cellular materials within the door panels in side-impact accidents; development of injury prediction model to out-of-position occupants from frontal- and side- airbags using Design-of-Experiment methodologies; and the estimation of the relative driver fatality risks of two colliding vehicles using some quantitative measurements. A detailed methodology is developed for each application, and the results present several new technologies that can be implemented to enhance the safety performance of road vehicles. These goals are achieved through the use of finite element approaches, multi-body dynamic analyses and Design-of-Experiment statistical methods.

Book Description
This important study focuses on the way in which structures and materials can be best designed to absorb kinetic energy in a controllable and predictable manner. Understanding of energy absorption of structures and materials is important in calculating the damage to structures caused by accidental collision, assessing the residual strength of structures after initial damage and in designing packaging to protect its contents in the event of impact. Whilst a great deal of recent research has taken place into the energy absorption behaviour of structures and materials and significant progress has been made, this knowledge is diffuse and widely scattered. This book offers a synthesis of the most recent developments and forms a detailed and comprehensive view of the area. It is an essential reference for all engineers concerned with materials engineering in relation to the theory of plasticity, structural mechanics and impact dynamics. - Important new study of energy absorption of engineering structures and materials - Shows how they can be designed to withstand sudden loading in a safe, controllable and predictable way - Illuminating case studies back up the theoretical analysis
